Document Summary
Interested in genes that reside within the cell. Molecular genetics: tend to look for things that can combat disease and can also look at the exact genetic makeup. Blueprint: hox genes all shared by invertebrates and vertebrates. Genes are turning on and off of things. Somatic cells- everything that is not a sex cell. Stem cells- when they are present in the embryo they totipotent (undifferentiated; cell can turn anything it wants to) Got to make proteins for the body protein synthesis replicates. Provides increase surface area for metabolic reactions to take place. The more surface area, the more things that can occur. Unzips matching nucleotides two copies of the dna. 1 strand original / 1 strand synthesized mediated by enzymes. Proteins- essential for life, a typical protein can be made up of 200 amino acids. Amino acids- 20 types of amino acids and 9 of them are essential. Polypeptide chains- chains of amino acids linked together.
