BIO 105 Lecture Notes - Lecture 19: Eth, Protein Structure, Transgene
Document Summary
Structure depends on the order of the amino acids. No change because they code for the same amino acid; still a mutation. May or may not change the sequence, we don"t know. Addition or deletion of a base shifts reading. Reading frame: start codon, codon, codon, . stop codon. Frame shift mutation shifts the reading frame if you add/delete nucleotide bases. Can add/delete 1, 2, 4, 5, 7 if you add or take away 3/multiples of three, you are just adding or deleting an entire amino acid no shift in the reading frame (still has an effect) The big red pig ate the red rag. Insert: the big res pig dpi gat eth ere dra g gibberish. Deleteion: the big rep iga tet her edr ag gibberish. Delete: the big pig ate the red far fine. Mutations in gametes don"t effect you, but can effect your children. Mutations in somatic cells can effect you. Provide genetic variation- raw material for evolution.
