Answer:
A.) Core
Explanation:
Core definition: a central and often foundational part usually distinct from the enveloping part by a difference in nature.

<h3>What is anatomy?</h3>
Anatomy is a science that deals with the structure of the body of living organisms. We know that the structure of the body of an organism holds a lot of connection to the evolutionary history of the organism hence it can be used to predict the behavior of an organism such as the kind of things that organism may feed on.
When you are able to compare the jaw structure of all the organisms, then you could clearly see the relationship between the given jaw structure and that of other species hence what the specie eats can be obtained by extrapolation.

Answer:
A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.
Explanation:
In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.
But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which less transcription will occur.
