Answer: DNA Polymerase

Explanation:

Synthesis along the lagging strand is discoutinously synthesized in the 5' to 3' direction. RNA primase synthesizes short RNA primer to which deoxyribonucleotides are added by DNA polymerase. Each okazaki fragments has its own primer RNA.

DNA synthesis continues until the primer and previously added okazaki fragment is encountered.

The RNA primer is removed by DNA polymerase using exonuclease activity and is replaced with deoxyribonucleotides by DNA polymerase

The enzyme is DNA polymerase
