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.

Identical heat lamps are arranged to shine on two identical containers, one containing water and one methanol (wood alcohol), so that each liquid absorbs the same amount of energy minute by minute. The covalent bonds of methanol molecules are nonpolar, so there are no hydrogen bonds among methanol molecules. Which of the following graphs correctly describes what will happen to the temperature of the water and the methanol?
