Question

How many molecules are found in one Histone unit? (a)1 (b) 2 (c) 4 (d) 8​

Answer 1

Answer:

D. 8 cause its the right answer

Answer 2

There are d) 8 molecules in one Histone unit.

Explanation:

• Histones are proteins that aid in the packing of DNA into chromatin fibres. Histone proteins are positively charged proteins that attach to negatively charged DNA with arginine and lysine amino acids.

• There are 4 core Histones are H2A, H2B, H3, and H4. Histone is called an octamer because it is made up of two H3, H4 dimers and two H2A, H2B dimers. The DNA is locked in place on the nucleosome by linker histones, which can be released for transcription.

• Histones can be manipulated to modify how much DNA is packaged. The addition of a methyl group to histones improves their hydrophobicity. This leads to DNA packaging that is very tight.
