Induction

Virus DNA detaches, may
carry donor DNA with it

Virus DNA integrated into
donor DNA at specific site

Virus DNA enters
Host (don or) cell

Lysis

Transducing
phage

Virus DNA replicates, coats
form, DNA carries both virus
and donor markers

Phage assembles

Recombination

Lysis

Normal
phage

Virus DNA not integrated into
chromosome. Virus DNA
replicates; coats form; host
DNA breaks down

Phage assembles. Some
coats have donor DNA,
some have viral DNA

Virus DNA enters
Host (donor) cell

FIGURE 14.4 Transduction: the transfer of genetic material from donor to recipient via virus particles. Two processes are shown: upper one is the
integration transduction and the bottom one is the common non-integration transduction.
