What is the function of DNA polymerase?

• A. It repairs damaged DNA
• B. It synthesizes new strands of DNA during replication
• C. It translates RNA into proteins
• D. It unwinds the DNA double helix

Answer: (B)

DNA polymerase is an essential enzyme in the process of DNA replication, which is crucial for cell division and the maintenance of genetic integrity. Its primary function is to synthesize new strands of DNA by adding nucleotides to a pre-existing strand, following the base-pairing rules. During replication, DNA polymerase ensures that the genetic material is accurately copied so that each new cell receives an exact copy of the DNA. While there are other important processes involving different enzymes, such as the unwinding of the DNA double helix by helicase or the repair of damaged DNA, DNA polymerase specifically focuses on the creation of new DNA strands. This process helps maintain the continuity of the genetic code across generations of cells.
