Final answer:
DNA polymerase is the enzyme responsible for the synthesis of a primer for initiation in DNA replication. The primer is a short segment of RNA that provides a starting point for DNA synthesis.
Step-by-step explanation:
DNA polymerase is the enzyme responsible for the synthesis of a primer for initiation in DNA replication. The primer is a short segment of RNA that provides a starting point for DNA synthesis. During replication, DNA polymerase adds nucleotides one by one to the growing chain, using the primer as a template. It extends the primer by synthesizing a complementary DNA strand.
