Which statement best describes the role of DNA in generating new cells during development?

• A. It provides energy for cell division.
• B. It acts as an enzyme to speed up reactions.
• C. It directly codes for cell membrane synthesis.
• D. It provides a template for accurately duplicating genetic information in daughter cells.

Answer: (D)

During development, making new cells relies on passing the organism’s genetic information to each daughter cell. DNA’s key role is to serve as the template for copying the genome so every new cell ends up with an nearly identical set of genetic instructions. In replication, the two DNA strands separate and new complementary strands are built on each old strand by DNA polymerases, producing two identical copies in a semi-conservative way. This fidelity preserves the genetic blueprint across many rounds of cell division, which is essential for proper development and differentiation. Energy production and enzymatic activities come from cellular metabolism, not from DNA itself, and DNA does not directly code for membrane synthesis—the genes encode proteins that drive those processes. So the best description is that DNA provides a template for accurately duplicating genetic information in daughter cells.
