BIO 110 Lecture Notes - Lecture 12: Flavin Adenine Dinucleotide, Messenger Rna, Phosphodiester Bond
Document Summary
The central dogma - transfer of information through different molecules. Replication dna transcription rna translation protein. Phosphodiester bond - holding backbone of dna together. Adenine in lots of important places: atp (one of 4 bases), coenzyme a, flavin adenine dinucleotide, nad+, caffeine. Messenger rna (mrna) - codes for polypeptide. Transfer rna (trna) - brings amino acids to mrna. Ribosomal rna (rrna) - components of ribosomes. Small nuclear rnas (snrnas) - part of ribonucleoprotein complexes. Micrornas (mirnas) - function of gene regulation. Small interfering rnas (sirnas) - help defend against genomic parasites. Nmp - one phosphate (ex: amp, gmp) Ndp - two phosphates (ex: adp, gdp) Ntp - three phosphates (ex: atp gtp) Distance for purine + pyrimidine is similar regardless of pair. Dna is naturally made to denature and renature. Dna can be unzipped by breaking hydrogen bonds. Nucleic acids can form more than a double helix. More g and c"s tighter gene increases melting point.
