Answer:
A. The tails do not interact with the DNA
Explanation:
The acetylation refers to the transfer of the acetyl group from Acetyl-CoA to the N-terminal of the histone protein.
Lysine residues (positively charged amino acid) are present at the end of the N-terminal of the histone protein which is neutralized by the acetyl group.
This loses the compaction between the positively charged histone and the negatively charged DNA and the DNA becomes more relaxed. This relaxed state allows the transcription factors to easily bind the DNA and therefore the DNA becomes transcriptionally active.
Thus, Option-A is correct
The layers and structures the needle passed through are- epidermis, dermis, subcutaneous layer or hypodermis, connective tissue layer and muscle.
The epidermis is the outermost layer of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The connective tissues connects, binds and separates other tissues or organs. Muscles are soft tissues found in the body. They function to produce force and motion.
No choice given but this type of research deals with the response to drugs of people according to their genetic make-up. Pharma means drugs and genomics is to do with the genes. The purpose is to suit the drugs to a person's actual genetic make-up so the drugs will be compatible with their genes.
When new information leads to new and different conclusions, it is important to be able to adapt to the most up-to-date conclusions. If conclusions are rigid and fixed regardless of any new information that may come to light, then they are not truly based on the facts under discussion.
