What is the significance of germ cells in relation to DNA?

• A. Germ cells store energy.
• B. Germ cells undergo changes to become reproductive cells (egg and sperm).
• C. Germ cells are the main component of blood.
• D. Germ cells are used for muscle contraction.

Answer: (B)

This question is about how germ cells relate to DNA and heredity. Germ cells are the precursors to eggs and sperm. They undergo meiosis, which halves the chromosome number so fertilization restores the full set in the offspring. During this process, genetic recombination and independent assortment create new combinations of DNA, increasing genetic diversity in the next generation. So germ cells are the vehicle that passes DNA from parents to offspring, shaping inherited traits. The other ideas don’t fit because energy storage, components of blood, and muscle contraction are functions of other cell types and tissues, not the role of germ cells in heredity.
