Document Summary

Nucleic acids: composed of nucleotide chains: function in storage and transmission of genetic info, have structural and catalytic roles (ribozymes, two types of nucleic acids: Info stored used to govern cellular activities through formation of rna messages. Thought to have been the carrier of genetic information before dna, way older than dna, but degenerates way faster. Composition (3 parts: five-carbon sugar (ribose) (1", nitrogenous base (ring with n in it, phosphate group (5") Oh group attached to 3" forms ester with phosphate group on 5" of another nucleotide to form the chain (sugar-phosphate linkages) Consist of single strand, fold back on themselves to form secondary and tertiary structures trna forms clover leaf structure: two types of bases: Pyrimidines - smaller, single ring (c and u/t) Purines - larger, two-ringed (a and g: double strands are held together by double bonds, 393-398. Dna composition: basic building block is nucleotide. 1st component: deoxyribose 5-carbon sugar (missing oh group on 2" c)
