#Unit 3. Fundamental Processes

Bacteriophage λ, has two mode of life cycle;  lytic and lysogenic.  In the lytic growth

a) a single Cro dimer is bound to OR3; this site overlaps PRM and so Cro represses that promoter

b) Repressor bound at OR1 and OR2 blocks RNA polymerase binding at PR, repressing transcription from that promoter

c) PR and PL binds RNA polymerase and directs transcription of lytic genes

d) During lytic, PRM is on while PR (and PL) are off

Find the correct combinations of lytic growth.
