Use sentences. answers should be clear and easy to
understand.
Make sure you are actually addressing the question asked. Simply stating facts is not
the same as distinguishing, illustrating, explaining, comparing, and so on.

For example, How does histone acetylation around promoter regions increase
gene transcription? is NOT adequately answered by histone acetylation lessens
the positive charge of the histone so DNA cannot wrap around them as tightly.
While the given answer is true, it does not link the wrapping of DNA around
histones with transcription rates, and therefore, does not fully answer the
question.
For each question the maximum answer length is 300 words.
