I need help ASAP! During replication, the strands of a double stranded DNA separate when the bonds are broken between their paired bases.
Explain why, in terms of the genetic code, it is important that the molecule separated between the bases and not at some other point. (Remember the bases are letters that spell out specific traits for the organisms).

What are the probable phenotypes of their offspring

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
