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
Answer:
Hypotonic
Explanation:
Tap water contains a lot of solutes and ions that are absent in distilled water. The solution that has more solutes (more dissolved solids) will be the <em>hypertonic</em> solution.
Here, distilled water has no solutes, making it <em>hypotonic</em>.
It's both! Scientists really can't agree on it.
No they are lower because they don't go so high.
This is true they are the products of photosynthesis and the reactants for aerobic respiration.
