Phage lambda must first attach to the host cell surface and insert bacteriophage DNA by contracting the sheath proteins. Upon entering the host cell, the linear double-stranded phage DNA is circularized to prepare for capsid protein synthesis. Next, the phage replicates the DNA genome and packages the DNA into capsids. Finally, the phage lyses the host cell and progeny phagesare released. A. occurs at random leading to the prevention of some key steps in the viral replication cycle. B. allows host cells to remember infection by copying small sections of viral DNA into RNA. C. destroys the infected cells and halts viral production. D. recognizes viral mRNA and prevents further viral gene expression.
