Which one of the following statements about Histones is wrong? (1) Histones are organized to form a unit of 8 molecules (2) The pH of histones is slightly acidic (3) Histones are rich in amino acids – Lysine and Arginine (4) Histones carry positive charge in the side chain

Correct option:(4)Histones carry positive charge in the side chain

Soulution:

  • Histones are rich in basic amino acids residue lysine and arginine with charged side chain.
  • Five types of histone proteins i.e., H1, H2A, H2B, H3 and H4.
  • Four of them occur in pairs to produce a unit of 8 molecules (histone octamer).
  • pH of histones is basic.
