BIOL 1001 : BIO 1001 Notes TEST 2
Document Summary
Termination: translation = info in rna makes protein (protein synthesis) Bonds must form between amino acids; amino acids are energy. Codon triplet of nucleotides/codes for one specific amino acid: endoplasmic reticulum (er) rough & smooth; where ribosomes are. Aug start codon (atg = aug) Methionine (trna) first amino acid in protein normally. Aug (met) gau (asp) uug (leu) aga (arg) [stop: how do cells control which proteins they make? located. They regulate: transcription/translation (stable mrna vs unstable mrna; active stop)/modification of proteins/degradation. When an rna virus infects the cell, it injects its genome consisting of stranded mrna double-stranded rna. Rna interference destroys the viral rna, preventing the formation of new viruses: b. synthesis of many proteins is controlled by genes encoding microrna. 3 types: point mutation/insertion mutation/deletion mutation (all frame shift mutations) Point mutation = change in one base pair (has most varied effects) Most mutations = neutral or harmful few mutations = advantage to individual.
