Which one of the following statements about histones is wrong?

Options

  1. AHistones are organized to form a unit of 8 molecules.
  2. BThe pH of histones is slightly acidic.
  3. CHistones are rich in amino acids - Lysine and Arginine.
  4. DHistones carry positive charge in the side chain.

Correct answer

B. The pH of histones is slightly acidic.

Step-by-step solution

Histones are rich in the basic amino acids residues like lysine and arginine having positively charged side chains. Four of them occur in pairs to produce histone octamer or nu-body (two copies of each).
