Question

Consider the following statements regarding genetic material and cell divisions:

I. Genetic traits are carried by DNA.

II. RNA is a double-stranded molecule.

III. Mitosis leads to the formation of new cells, contributing to growth.

Which of the statements given above is/are correct?

  1. A. Only I and II
  2. B. Only I and III (Correct answer)
  3. C. Only II and III
  4. D. I, II and III

Correct Answer

Option B — Only I and III

Detailed Solution & Explanation

The correct answer is Only I and III.

Key Points

  • Statement I: Genetic traits are carried by DNA ✓.
  • Statement II: RNA is typically single-stranded, NOT double-stranded — DNA is double-stranded (Statement II is incorrect ✗).
  • Statement III: Mitosis produces genetically identical daughter cells, enabling growth and tissue repair ✓.
  • Statements I and III are correct.
