ANSWER KEY
... NO. This phage contains an amber mutation in a gene required for phage DNA replication, the first step of the lytic life cycle. Since the bacterial strain does not contain an amber suppressor tRNA, no phage replication--and thus no cell lysis—will occur during the infection. b) Predict whether all, ...
