Reason : Histones are 5 major types H1, H2A, H2B, H3 and H4.
  • a)
    If both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • b)
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  • c)
    If Assertion is true but Reason is false.

Assertion and Reason Analysis
Assertion: Histones are basic proteins of major importance in packaging of eukaryotic DNA.
Reason: Histones are 5 major types H1, H2A, H2B, H3 and H4.

Explanation
- Histones and DNA Packaging: Histones are indeed basic proteins that play a crucial role in packaging eukaryotic DNA. They help in organizing and condensing DNA into chromatin structure.
- Types of Histones: Histones are categorized into five major types, which are H1, H2A, H2B, H3, and H4. Each of these histone types has specific functions in the packaging and regulation of DNA.
- Chromatin Formation: When DNA wraps around histone proteins, it forms nucleosomes, which are the basic repeating units of chromatin. These nucleosomes further compact into higher-order structures to form the bulk of eukaryotic chromosomes.
- Explanation of Assertion and Reason: While both the Assertion and Reason are true, the Reason provided does not directly explain why histones are essential for packaging DNA. The Reason merely states the types of histones without elaborating on their role in chromatin organization.
Therefore, option B is the correct choice where both the Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
