Document Summary
Dna: contains a 3" end with a hydroxyl group and a 5" end with a phosphate, numbering begins at the 5" end, purines: adenine/guanine, pyrimidines: thymine/cytosine/uracil, thymine is used in dna instead of uracil because it is more specific to pairing with adenine, and fits better into the double strand, cytosine can also be converted to uracil so thymine is used so that the cell can tell if there is a mutation, this is not as important in rna because there are so many copies that one point mutation almost becomes negligible (the blueprint is more important) Apparatus: processes lipids and proteins by either adding carbohydrates of splitting proteins (proteolysis, sorts proteins to their proper locations, packages different materials into secretory vesicles which release it out of the cell (exocytosis, cis; close to the er, trans; near the membrane, medial; between cis and trans.
