Chapter 11, Problem 21PDQ

Summary Introduction

To review:

The formation of a closed ring by the lambda phage DNA (deoxyribonucleic acid) in a host cell.

Introduction:

Lambda phage is an enterobacteria phage that infects Escherichia coli. It is made up of a head, a tail, and tail fibers, and the phage double-strand linear DNA is enclosed in the head. It performs both lytic and lysogenic cycles in the host. In the lytic cycle, the replication of lambda phage is followed by host cell lysis, and in the lysogenic cycle, the viral genome gets integrated into the host genome and replicates there.
