Transcript of DNA
•the making of proteins Protein Protein Synthesis •the order of DNA bases is the code or pattern for the making of specific proteins DNA is in the shape of a double helix or a twisted ladder.
The Double stranded shape is necessary so that DNA can unzip and create the template for two daughter cells. •The two steps to protein synthesis are:
2. Translation Step number 1: Transcription •Occurs in the nucleus
•The process of making mRNA from the DNA template.
.Nucleotides in the mRNA form base pairs with their complementary nucleotides in the DNA.
Then the mRNA strands breaks away and goes to the cytoplasam and the DNA strands rejoin. Codons: Codons are formed by a group of three nitrogenous bases in mRNA.
Each Codon is code for one Amino Acid. Theronine Lysine Leucine Alanine Step 2: Translation Translation is the process of converting the information in a sequence of nitrogenous bases in mRNA into a sequence of amino acids in protein.
It occurs in the ribosomes and cytoplasm.
tRNA carrying the appropriate attach to the mRNA in the ribosome then a new tRNA carrying a new amino acid attach next to the original tRNA and the amino acid that it's carrying forms a peptied bond with the original one. This continues until it reaches the stop codon and a protien is formed. tRNA Peptide bond Protien Protein Ribosome mRNA Over Production and under production Over production of proteins has its advantages and disadvantages.
An advantage would be quick healing.
A disadvantage would be cancer.
Under production or production of proteins at the wrong times would cause disorders like sickle cell.
