What is the primary function of DNA polymerase?

✅Explanation:
DNA polymerase is a crucial enzyme responsible for synthesizing new DNA molecules by copying the existing DNA template strand. This process, known as DNA replication, is essential for cell division and growth, as well as for passing genetic information from one generation to the next.

• Here's why the other options are incorrect:
-b) Helps in RNA replication: While RNA polymerase is another important enzyme involved in nucleic acid synthesis, it specifically synthesizes RNA molecules from DNA templates, not new DNA.
-c) Helps in protein synthesis: Protein synthesis occurs in the cytoplasm using RNA as a template, and does not directly involve DNA polymerase.
-d) None of these: Based on the known functions of DNA polymerase and its role in DNA replication, this option is not accurate.
