Document Summary
Bio130 lecture 3 dna and rna. Three parts of a nucleic acid phosphate group sugar: ribose or deoxyribose base, a, t, c, g, or u. Bases two types: purines and pyrimidines purines: guanine and adenine pyrimidines: thymine, uracil, cytosine. Rna: deoxyribose, g, c, a, t, ribose, g, c, a, u, much more reactive due to hydroxide group, it is more labile than dna, meaning it degrades more easily at high temperatures or alkaline environments. This is not necessarily a bad thing, we don"t want rna to stick around forever, we want it to be relatively easy to break down. Nucleic acid nomenclature base plus sugar is a nucleoside in this case nucleoside monophosphate has a base, sugar, and phosphate nucleoside diphosphate has a base, sugar, and two phosphates. Which of the following is an rna nucleotide: a phosphate group, adenine, and ribose, a phosphate group, guanine, and deoxyribose c, a phosphate group and adenine thymine and ribose.
