Answer:
Explanation:
The Escherichia coli catabolite gene activator protein (CAP) is a DNA binding protein involved with the transcription of several genes, including those that code for enzymes involved in the metabolism of certain sugars (i.e. lactose, maltose, and arabinose.) <u>Basically, CAP is responsible for the global regulation of carbon utilization.</u> Upon binding cAMP, CAP binds to a conserved DNA sequence from which it can either activate or repress transcription initiation from various promoters. In some cases clusters of several promoters are all controlled by a single cAMP-CAP complex bound to the DNA.
Once CAP has bound cAMP, the protein exhibits a higher affinity for a specific conserved DNA sequence. When the intracellular level of cAMP increases, the second messenger is bound by CAP and the cAMP-CAP complex binds to the DNA. Once bound, it is able to stimulate the transcription of the aforementioned genes. DNA bound by the CAP-cAMP complex is bent by ~90 degrees. This DNA bend, coupled with a protein-protein interaction between CAP and RNA polymerase is thought to be the mechanism by which CAP regluates transcription initiation on the chromosome.
Likely, B is the expected answer.

As one who has suffered health problems for more than 40 years due to the desire of certain chemical industries to make money by polluting my food, I can barely remain civil when discussing genetic modification. Plants with built-in pesticides are bad news on so many levels it would take a library of books to discuss them all. What, after all, is the benefit of efficiently producing poison?
Answer:
the flu cannot be "Cured" but can oly be surpressed so it in inactive. only the body white blood cells can kill and fully remove the virus.
this is questiponed because it is true that it is limited to only one person, but this person may not of even had the flue to begin with. the the second question is which flue did the person have. swine flu is deadly and cannot be removed with antibodies or antibiotics. which is a pain because this flue kills the body.
the second things that is questioned is, is the antibiotic stable enough for everyone?
everyone has a different immune structured in different ways. some antibiotics will not help certain people because of the lack of lipids and enzymes in the hosts blood. this can be fatal because the body has a natural buffer in the blood that the antibiotic can easily damage and kill the host.
