Why does lambda phage use different promoters to transcribe the cI repressor gene immediately after infection and in the lysogenic state?
Why does lambda phage use different promoters to transcribe the cI repressor gene immediately after infection and in the lysogenic state?
Answer
Lambda phage uses different promoters to regulate the expression of the cI repressor gene to ensure that the phage can efficiently establish lysogeny by producing the repressor protein immediately after infection to inhibit the lytic cycle and maintain a stable lysogenic state.
