BIOL130 Lecture Notes - Lecture 12: Nucleoside, Ribose, Adenine
Document Summary
Unit 2c: macromolecules nucleic acids: deoxy ribo nucleic acid (dna) Sequence of subunits in dna polymer directs rna synthesis: ribo nucleic acid (rna, rna directs ordering of aas in a peptide chain. Info stored as dna sequences enables living orgs to pass heredity information: also allows each cell to pass on heredity into to the next gen of cells. Deoxyribo nucleotides (to build dna): phosphate + deoxyribose + base (a, g, c, t, damp, dcdp, dgtp, ect (dntp, ribo nucleotides (to build rna, phosphate + ribose + base (a, g, c, u, amp, udp, gtp etc (rntp) Nucleic acids are polymers: nucleic acids are linear (unbranced) polymers of nucleotides. Each nucleotide consists of three parts: nitrogenous base, a 5-carbon pentose sugar, a phosphate. Components of nucleotides: nitrogenous bases, pyrimidine 1 ring (longer word, uracil. Thymine: purine 2 rings (shorter word, adenine, guanine.
