Questions and Answers
What is the difference between temperate phages and virulent phages?
Temperate phages can behave as prophages and integrate into the bacterial chromosome, while virulent phages can only lyse the host cell.
Explain the concept of transduction and cotransduction in bacterial recombination.
Transduction is the process of bacterial recombination mediated by bacteriophages, while cotransduction involves the simultaneous transduction of two genes that are close enough.
What is the significance of lysogeny in the life cycle of a bacteriophage?
Lysogeny allows the phage DNA to integrate into the bacterial chromosome, coexisting without lysing the host cell, and can be passed to daughter cells during replication.
