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.
Elaine is a police officer and a mother of a 17 year old son. One afternoon while cleaning her son's room, Elaine finds drugs in his backpack. She tells him
that she cannot allow drugs in her home and demands he tell her where they came from. In these two roles as police officer and mother, Elaine is experiencing:
B. role conflict
Answer:
Slower population growth means that women on average are having fewer children, which gives girls and women the opportunity to pursue education and careers and continue a positive cycle of schooling, autonomy and equal status. Slower population growth will also place a higher value on immigration.
Hope that helps!
Answer:
from the sun
Explanation: Energy enters the ecosystem from the Sunand exits after the organisms have taken as much as they need. Organisms release energy back into the biosphereas heat. Energy also enters the ecosystem from the interior of the Earth. It is usually in the form of heat, not the electromagnetic radiation from the Sun.
