Answer:
The answer here is C: the botanist
Explanation:
This is the only plausible answer because geologists study the earth's physical structure and substance. This has nothing to do with the mangroves, so this can't be the answer. The same goes for the anthropologist, who studies ancient human origins. The first option sounds ok, because zoologists study crabs, which are feeding directly on the mangrove trees, and maybe the decline of mangroves is due to them. But they would not be the first scientist to ask, which is the question. The first person to ask would be the botanist, who studies trees. They would be the most likely to know the answer.
Answer:
The correct answer is "Histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction".
Explanation:
Histone acetyltransferases (HATs) are regulators of gene activation and deactivation, achieved by the transference of an acetyl group from acetyl-CoA to histones. HATs function by the premise that histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction. Therefore, most of the times histone acetylation increases gene expression, because the acetylated gene is free from the histones and is able to be encoded.
Species form of a small cells under the water when the earth was contain some alive creature in it. It's a theory.
