In one experiment, another protein –protein interaction is used in place of that between CAP and polymerase. This is done by taking two proteins known to interact with each other, attaching one to a DNA-binding domain, and, with the other, replacing the carboxy-terminal domain of the polymerase a subunit (aCTD), which one is appropriate result of this experiment-
I. The modified polymerase can be inhibited if the appropriate DNA-binding site is introduced near the promoter.
II. The modified polymerase can be activated by the makeshift “activator” as long as the appropriate DNA-binding site is introduced near the promoter.
III. The activator having only to help polymerase bind to the promoter

geneticist is working with a new bacteriophage called phage Y3 that infects E. coli. He has isolated eight mutant phages that fail to produce plaques when grown on E. coli strain K. To determine whether these mutations occur at the same functional gene, he simultaneously infects E. coli K cells with paired combinations of the mutants and looks to see whether plaques are formed. He obtains the following results. (A plussign means that plaques were formed on E. coli K; a minussign means that no plaques were formed on E. coli K.)
How many cistron belong to these mutation?
