Assertion: Histones are basic proteins of major importance in packaging of eukaryotic DNA. DNA and histones comprise chromatin forming the bulk of eukaryotic chromosome.
Reason: Histones are of five major types and H1, H2AH2B, H3 and H4.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
Explanation:
Histones are basic proteins found in the eukaryotic chromosomes. These are rich in the amino acids lysine and arginine. Histone proteins are basic proteins consisting of 5 types – H1, H2A, H2B, H3, H4. DNA is coiled around it. It exists as octamers linked with H1.
