Final answer:
Primase is the enzyme that most closely resembles RNA polymerase because both synthesize RNA, but primase specifically creates RNA primers for DNA replication.
Step-by-step explanation:
The DNA replication enzyme that most closely resembles RNA polymerase is primase (c). Primase is the enzyme responsible for synthesizing a short RNA primer during DNA replication, which provides a starting point for DNA polymerase to begin synthesizing the new DNA strand. Both primase and RNA polymerase are enzymes that synthesize RNA. However, while RNA polymerase synthesizes RNA molecules for protein synthesis, primase synthesizes short RNA sequences that are complementary to the DNA strand, allowing DNA polymerase to add DNA nucleotides. DNA polymerase I, although it has the ability to remove RNA primers and replace them with DNA, and DNA polymerase III, the primary enzyme responsible for DNA synthesis, do not function in the same initial capacity of generating RNA molecules as primase does. Other enzymes mentioned, such as helicase and telomerase, play different roles in DNA replication and do not share the same function of primer synthesis as primase does.
