Question

Part A lain why it is to the advantage of bacteriophage lambda to tightly regulate the level of lambda repressor made in lysogenic E. coh cells Drag the words on the left to the appropriate blanks on the right to complete the sentences. Reset He high 1. If repressor level is too need to be inactivated before repressor vacates Oi and Og2 anid lytic growth is induced induction would be inefficient, as more repressor would low 2. If repressor level is too the cells might induce the lytic cycle without the bacteriophage being ready for release Submit Request Answer

Explanation / Answer

If the repressor level is too high, induction would be inefficient, as more repressor would need to be inactivated before repressor vacates OR1 and OR2 and lytic growth is induced.

If repressor level is too low, the cells might induce the lytic cycle without bacteriophage being ready for release.

(lambda repressor bind OL and OR sequences near PL and PR nd inhibit their transcription, which is necessary for lytic cycle)
