Hlo friend
Here is your answer
Answer:
The difference between histone and nonhistone is simple. Both are proteins, both provide structure to DNA, and both are components of chromatin. Their chief difference is in the structure they provide. Histone proteins are the spools about which DNA winds, whereas nonhistone proteins provide the scaffolding structure.
Explanation:
Chromatin reconstitution studies provide evidence that nonhistone chromosomal proteins play a key role in activation of histone gene transcription during the period of the cell cycle when DNA is replicated.

Answer:
- Histones are the basic proteins rich in basic amino acids arginine and lysine.
- They expose their surfaces with positive charges for attracting and hold and holding the DNA strands which have negative charges in their phosphates.
- Four types of histones (H2A, H2B, H3 and H4) form nu bodies over which DNA is wrapped to form nucleosomes.
- Nucleosomes are structural units of chromatin. H1 histone is used as a linker between adjacent nucleosomes. It helps in their coiling.
