One form of chromatin modification is acetylation, which is known to occur on positively charged histone tail amino acids, thus
Naya [18.7K]

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

Why is it important to use a weakened virus in a vaccine?
PolarNik [594]

If you used a full active virus, that defeats the point of a vaccine. You will trigger your immune response, but since you would just be injecting the virus, it will make you sick, and your body will be less effective at fighting the pathogens.

Viruses in vaccines are weakened, so they essentially will not "fight" back. They most importantly just contains the antigen markers so the body can trigger the immune response, quickly eradicate the pathogen, and build up the memory cells to that virus.

Injecting a virus that is not weak will just be the same thing as if you got the virus, you will likely get sick.
