A cell that has taken on a specific task, and cannot divide to form cells for another task. A cell that has yet to choose a specific task, and can divide and replace cells that do not reproduce. Stem Cells are needed because they could replace cells (such as brain cells or spinal cord cells) that have been destroyed and cannot reproduce. P.C.R. Stands for... Polymerase Chain Reaction Is mainly used for... Detecting genetic disorders. Because the human genome is so long, it would be impossible to look at every single gene in it P.C.R. speeds that up, by grabbing a small section of the DNA, analyzing it, and finding things like someone's risk of getting a genetic disorder Another, more recent, invention is Real-Time PCR, which is a machine that will perform PCR. (Wittwer and Farrar, 2011, n.p.). (Wittwer and Farrar, 2011, n.p.). Selective Breeding
Also Known As Artificial Selection. Although Selective Breeding doesn't sound familiar, many of us see examples of it every day in... The food we eat. House Pets + The Advantages and Disadvantages of Selective Breeding Pros: We can choose what traits plants and livestock will have. Flowers and animals can be made to look the way we want. Cons: Over breeding within a specific gene pool can intensify the bad traits as well, resulting in mutations that may hurt the offspring. Is... Farmers and Dog Breeders picking certain parents, who share a desirable trait, and breeding them in order to gain offspring with that trait. It is also a representation of how Charles Darwin's idea of Natural Selection works. Recombinant DNA
.................................................................... ............................................................. ..................................................... Is basically taking DNA from one organism, and putting it into another, or combining DNA from two organisms (Pray, 2008, n.p.). http://tailsnscalesks.blogspot.com/2011/05/new-cosmic-blue-glofish.html GloFish are an example of this.
They are Zebrafish with a green fluorescent protein added in. How can that help? If one animal has a weakness or a disease that another has immunity to, taking the immunity from one animal and putting it into the other could potentially eliminate tons of problems. If the research goes far enough, it could even be used in humans. http://www.wisdompanelpro.com/breedinfo/ Dangers Behind Transgenic Organisms? People worry about the side effects of DNA recombination Possible infliction of pain upon organisms being used for DNA recombinant testing Causing too much change to the world (Glenn, 2004, n.p.). (Glenn, 2004, n.p.). (Glenn, 2004, n.p.). Cloning: Humans, Genes, or Research? Creating exact genetic
copies of something. Human cloning attempts are only successful a small percentage of the time. Cloning for research receives similar objection to stem cell research, because, even if the embryo is a cloned one, it's still living + is done by replicating DNA exactly, mutations and all. (Bailey, n.p.). (Bailey, n.p.). 3 Types of cloning Gene cloning: Clones DNA molecules specifically (Bailey, n.p.). Organism Cloning: Copies an entire organism (Bailey, n.p.). Therapeutic Cloning: Cloning human embryos in order to further Stem Cell research (Bailey, n.p.). Topics Stem Cells
