The histone present in chromatin are basic proteins.
They contain 20 to 30 per cent arginine and lysine, two positively charged amino acids.

Total number of histone proteins present in chromatin with 20 nucleosomes

The major amino acids in histone protein of chromosomes are 1. histidine and tryptophan 2. arginine and lysine 3. tyrosine and tryptophan 4. cystine and tyrosine

Which of the following statement is true for the packaging of DNA in eukayotes? A. DNA is packaged with a set of basic protein called histone. B. Histone contain negatively charged amino acid in its side chain. C. DNA packed with histone octamer are called nuclesome. D. Nuclesome is further packed to form chromatin fibre.

Name the two basic amino acids that provide positive charges to histone proteins.

What would happen if histones were to be mutated and made rich in acidic amino acids such as aspertic acid and gultamic acid in place of basic amino acids such as lysine and arginine?
