Answer:

Please find the description of the steps involved in DNA replication below. The terms listed in the question are written in BOLD.

Explanation:

DNA replication is the process by which DNA molecule is duplicated in the genome to produce two identical copies. DNA replication, which must occur prior to any cell division, involves the following steps:

- An enzyme called DNA HELICASE unwinds the double strand of DNA into a Y-shaped replication fork.

- Another enzyme called DNA POLYMERASE attaches to the single strand of DNA to add nucleotides to the growing DNA molecule.

- An enzyme called DNA PRIMASE adds a short nucleotide sequence called PRIMER, which serves as foundation for DNA polymerase to act upon.

- The DNA polymerase adds nucleotides based on complementary base pairing rule i.e. A-T, G-C.
