Transcript: Basic Structure of DNA and RNA DNA A phosphate-deoxyribose polymer composes the backbone of the DNA adjacent sugars are connected by phosphodiester bonds nitrogenous bases are convalently bonded to the 1' carbon of the deoxyribose the two DNA strands are antiparallel the two strands are held together by hydrogen bonds between complementary bases adenine hydrogen bonds (base pairs) to thymine guanine hydrogen bonds to cytosine RNA Description of general bacterial genome bacterium's entire genetic information Description of general viral genome A virus has either DNA or RNA genes and is called a DNA virus or a RNA virus respectively. The vast majority of viruses have RNA genomes The nucleic acid comprising the genome may be single-stranded or double-stranded, & in a linear, circular or segmented configuration. Summay of steps of replication in bacteria The bacterial chromosome is circular. The replication process starts at a site called the origin. But instead of replicating in one direction around the chromosome, it replicates in two directions. This is called bidirectional replication as two replication forks move in opposite directions away from the origin. The forks will meet at the bottom of the chromosome and replication is terminated as the two chromosomes separate. The bacterial chromosome is also capable of initiating multiple replication forks. The processes of bidirectional replication and the concept of multiple replication forks are discussed in more detail in the replication laboratory. Summary of steps of transcription in bacteria 1.DNA unwinds/"unzips" as the Hydrogen Bonds Break. 2.The free nucleotides of the RNA, pair with complementary DNA bases. 3.RNA sugar-phosphate backbone forms. (Aided by RNA Polymerase.) 4.Hydrogen bonds of the untwisted RNA+DNA "ladder" break, freeing the new RNA. 5.If the cell has a nucleus, the RNA is further processed and then moves through the small nuclear pores to the cytoplasm Summary of steps of translation 1. Initiation •The small subunit of the ribosome binds to a site "upstream" (on the 5' side) of the start of the message. •It proceeds downstream (5' -> 3') until it encounters the start codon AUG. (The region between the cap and the AUG is known as the 5'-untranslated region [5'-UTR].) •Here it is joined by the large subunit and a special initiator tRNA. •The initiator tRNA binds to the P site (shown in pink) on the ribosome. •In eukaryotes, initiator tRNA carries methionine (Met). (Bacteria use a modified methionine designated fMet.) 2. Elongation •An aminoacyl-tRNA (a tRNA covalently bound to its amino acid) able to base pair with the next codon on the mRNA arrives at the A site (green) associated with: an elongation factor (called EF-Tu in bacteria) GTP (the source of the needed energy) •The preceding amino acid (Met at the start of translation) is covalently linked to the incoming amino acid with a peptide bond (shown in red). •The initiator tRNA is released from the P site. •The ribosome moves one codon downstream. •This shifts the more recently-arrived tRNA, with its attached peptide, to the P site and opens the A site for the arrival of a new aminoacyl-tRNA. •This last step is promoted by another protein elongation factor (called EF-G in bacteria) and the energy of another molecule of GTP. Note: the initiator tRNA is the only member of the tRNA family that can bind directly to the P site. The P site is so-named because, with the exception of initiator tRNA, it binds only to a peptidyl-tRNA molecule; that is, a tRNA with the growing peptide attached. The A site is so-named because it binds only to the incoming aminoacyl-tRNA; that is the tRNA bringing the next amino acid. So, for example, the tRNA that brings Met into the interior of the polypeptide can bind only to the A site. 3. Termination •The end of translation occurs when the ribosome reaches one or more STOP codons (UAA, UAG, UGA). (The nucleotides from this point to the poly(A) tail make up the 3'-untranslated region [3'-UTR] of the mRNA.) •There are no tRNA molecules with anticodons for STOP codons. (With a few special exceptions: link to mitochondrial genes and to nonstandard amino acids.) •However, protein release factors recognize these codons when they arrive at the A site. •Binding of these proteins —along with a molecule of GTP — releases the polypeptide from the ribosome. •The ribosome splits into its subunits, which can later be reassembled for another round of protein synthesis. Basic concept of how an operon functions In genetics, an operon is a functioning unit of genomic material containing a cluster of genes under the control of a single regulatory signal or promoter. The genes are transcribed together into an mRNA strand and either translated together in the cytoplasm, or undergo trans-splicing to create monocistronic mRNAs that are translated separately, i.e. several strands of mRNA that each encode a single gene product. The result of this is that the genes contained in
Transcript: People will develop more diseases as bacterias can mutate and be even more dangerous since there are no vaccines for it. And creating a vaccine for one person can take a months nor years if it succeeds. If creating a vaccine for one person is taking a long time how would it be if you are producing vaccines for billions of people. However, there are some bacterias that can help Importance Mutation (mutation) technology, gene recombination technology, gene replacement, amplification technology A series of genetic modification techniques such as Atractylodes macrocephala, transfer, recombination and modification of extrachromosomal genetic materials, and the structure and properties of some biological genetic materials (chromosomal DNA, RNA, plasmid DNA) Reasons: Found and confirmation : Screening and constructing transforming and degrading microorganisms, improving genetic stability of Engineering bacteria, providing more scientific, rapid, accurate and diverse environmental monitoring and assessment techniques, and helping to synthesize biococoa Screening and construction of transformed microorganisms Industry and Environment Microbial genetics will be helpful to increase these(antibiotics or medicine related to microbes) products productivity by microbial technology. This means that the health industry are earning heaps of money because of the fact that people are needing so much treatment and researches to be able to cure. Citations Microbial genetics is a branch of genetics that studies viruses, bacteria, small fungi, single-celled animals and plants.Microorganisms are good materials for genetic research because of their small size, short life cycle, rapid propagation on simple synthetic media, and the ability to process large numbers of individuals under the same conditions One is to use the traditional mutation breeding and cross breeding technology to screen and cultivate highly effective strains of microorganisms.The strains have been used in the treatment of printing and dyeing wastewater, pesticide production wastewater and tailings wastewater, as well as in the removal of petroleum pollution and garbage degradation. Microbial Genetics Provide more scientific, fast, accurate and diverse environmental monitoring and environmental protection. Environmental assessment techniques In this field, biodegradable materials synthesized by microorganisms have attracted wide attention and have broad application prospects. For example, microbial fermentation is the main way to obtain biodegradable plastics at present. The materials needed for production in such techniques are obtained from the fermentation process of a particular microorganism, which is the fermentation product of a microorganism and a specific substrate. Relevant microbial genetic techniques help to screen, cultivate, domesticate and recombine engineered fermentation bacteria in such technologies, thereby introducing new metabolic pathways, synthesizing novel polymers, broadening the use of substrates, increasing production speed and reducing production costs.

Helping to synthesize biodegradable new materials Importance Another way is to use genetic engineering technology to construct efficient transformation and degradation engineering bacteria. Microbial genetics promotes the development of production. The principle of improving the final product by eliminating repression has been applied to the fermentation of amino acids and nucleotides with remarkable yield increase. The application of recombinant DNA technology in industry, agriculture and medicine is more difficult to estimate, and recombinant DNA technology is also the product of microbial genetics research. Microbial genetics research has also made an important contribution to medical and health services, especially in the detection of carcinogenic

Transcript: Cognition: - 25% of all cases - the embrio inherits both copies of chromosome 15 from the mother. - How does this happen? - This is more likely to happen in older women than younger women. - This can cause additional genetic problems or conditions - Sex hormone levels are typically low A disorder of Chromosome 15 Speech: Mode of Inheritance - delayed speech Appetite Disorder: Detecton - Their findings showed that heart rate variability, an indicator of ANS function, was not normal in people with PWS - in a healthy person, the time between one hearbeat and the next varies considerably during a meal because the ANS is actively regulating the body's response to food and body flow. - in people with PWS, hearbeates were far too regular after a meal. Other Common Concerns - have a high risk of cardiovascular disease - An Australian study reveals that people with PWS may have an impaired autonomic nervous system. This discovery opens up a new way of looking at their appetite issues. - autonomic nervous system: controls our inner organs, including our gut, heart, liver, and blood vessels. it responds moment-by-moment to the body's needs. Clinical Description of the Disorder - Motor milestones are typicallt delayed one to two years -Physical and occupational therapies help promote skill development and proper function Behavior Issues: Other interesting info. Weight and Behavior - IQs range from low to average - those with normal IQs typically have learning disabilities - Problem areas: attention, short term auditory memory, and abstract thinking Treatment - Compulsive eating and obsession with food usually begin before age 6. - The urge to eat is phsycological and overwhelming; it is difficult to control and requires constant watch. INTRODUCTION - the embrio has three copies of chromosome 15 - two from the mother (trisomy 15) - later the father's chromosome 15 is lost - has the same result as deletion --> the baby does not have the Prader-willi gene - although there are two copies of the mothers chromosome 15, the key genes in the PWS region are turned off - Currently, there is no cure for PWS. - Treatment is based on curing specific symptoms of the disorder as they arise. - Human growth hormone (HGH): Increases hight, deacreases body fat, increases muscle mass, improves weight distribution, increases stamina, and increases bone mineral density. it can also help behavioral problems - the inibility to control food intake is the biggest opstical that still has no cure; however, they can use anti-obesity drugs. - sleep problems can be helped with modafinil. Motor Skills: - Infants and young children with PWS are typically happy and loving, and exhibit few behavior problems. - Most older children and adults with PWS have difficulties with behavior regulation, manifested as difficulties with transitions and unanticipated changes. - The changes in behavior usually coincide with the uncontrollable need to eat Sexual Development: Scoliosis: can occur early; may be difficult to detect without X-ray. Diabetes mellitus, type II: Secondary to obesity; responds well to weight loss; screen obese patients regularly. Sleep disturbances: hypoventilation and desturation during sleep are common, as is daytime sleepiness Skin picking: a common, sometimes severe habit Dental problems: may include soft tooth enamal, thick sticky saliva, poor oral hygiene, and teeth grinding. GENETICS - less than 5% of cases - casued by an imprinting defect inhereited from the fathers chromosome 15 (region q11-q13). - This defect will not allow the normal expression of genes that are active on the chromosome 15 from the father and needed for normal development. - To identify imprinting defects on chromosome 15 requires specialized laboratory techniques available in ony a few genetic labs conducting research on PWS. Developmental Concerns Prader-Willi Syndrome (PWS) Birth - 2 years of age: - Hypotonia 2 years - 6 years: - Hypotonia - Developmental delay 6 years - 12 years: - continous developmental delay - Excessve eating with central obesity if uncontrolled 13 years - adulthood: - Cognitive disabilities; usually mild mental retardation - Excessive eating - behavior problems: temper tantrums, perseverative and compulsive-like behaviors Paternal Deletion ** Every case of PWS is due to the baby failing to recieve active genes from a specific section of the fathers chromosome 15 --> there are three different ways this can happen... - 70% of all cases - genes from chromosome 15 from the father is missing --> deletion. - common deletions are now classified as Type 1 or Type 2 depending on the size of the deletion. Maternal Uniparental Disomy (UPD) - 1:8,000; 1:25,000; most likely 1:15,000 - occurs in males and females equally - occurs eaqually in all races Autonomic Nervous System Sources: -http://www.pwsausa.org/syndrome/index.htm -http://www.disabled-world.com/disability/types/prader-willi-syndrome.php
