BIOL 1202 : Test 1
Document Summary
Loving water and hating water, grab onto substrates to ball up more. So specific that it can bind to one and do one thing then bind to a different one and do something different. Change active site and can change quality of functioning: 50 trillion cells that determine what it can do. Eukaryotic cell: transcription in nucleus: mrna, translation in cytoplasm: protein, dna rna protein. Language barrier: nucleotides, dna: 4 nucleotides, rna: 4 nucleotides, protein: 20 amino acids on a polypeptide strand. Genetic code: consists of codons, triplets of nucleotides, aug: methionine (start, 64 possible combinations, codes for one specific amino acid, three stop codons: uaa, uag, uga, table 10-3 in power point will be on exam 1. Translation: protein synthesis: requirements, mrna trna rrna, atp: energy, steps. Initiation: elongation: adding on amino acids to make a longer polypeptide chain, termination. Uv sensitive: folate requires for dna synthesis and cell division.
