Mcbio 316 – Exam 1 Page 1 (5) 1. Strains with a mutD mutation
... Strains with a mutD mutation have a mutator phenotype. When mutD strains are growing fast (e.g., in rich medium) the frequency that mutations accumulate is much higher than when they are growing slowly (e.g., in minimal medium). Why? ANSWER: More DNA replication occurs during fast growth than during ...

... Termination codons are recognised by ‘release factor’ proteins (RF1/RF2, RF3). RF1 or RF2 bind to stop codons in the A site of ribosomes, and activate the ribosome to hydrolyse the adjacent peptidyl tRNA (in the P site), to release the protein. RF3 releases the RF1 or RF2. Finally, RRF (ribosome rec ...
