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
Water is a polar molecule bcz oxygen bears partial negative charhe and hydrogen bears partial positive charge. This results in extensive hydrogen bonding btween water molecules. The temperature is another way of saying the average kinetic energy of gases liquids or vibration for the case of solids. The Heat Capacity is the ability of matter to absorb thermal energy. Water's specific heat is defined as one. Water has high heat capacity because it can store heat in many ways. Which makes its capacity higher than anything
Answer:
4.Cell wall protects the cell whiles organelles are found in the cell itself which is having the cell wall
