Option (a)

Enzymes involved in DNA replication:

  • DNA helicase – DNA helicase separates the strands into a Y-shaped structure known as the replication fork by severing the hydrogen bonds between base pairs.

  • RNA primase: This enzyme creates primers, which are short RNA sequences. These primers act as the initial step in the synthesis of DNA.

  • DNA polymerase: They are in charge of elongating the existing strand to form the new one.

  • DNA ligase joins the pieces of the Okazaki genome (small fragments formed during the replication of double-stranded DNA).
