Expert Solution

Step 1

A set of enzymes known as DNA polymerases catalyse the synthesis of DNA during replication. It is in charge of the process of DNA replication, in which a double-stranded DNA molecule is duplicated into two separate DNA molecules that are identical to one another. DNA polymerases come in a variety of forms in both eukaryotes and prokaryotes. Specifically in prokaryotes, DNA polymerase I is involved in lagging strand replication and is involved in the synthesis of short sections of DNA during excision repair, the removal of RNA primers, and filling in the spaces between Okazaki fragments. While eukaryotes use a complex technique that uses DNA ligase and PolC to repair or fill in gaps in DNA. So both DNA gaps can be filled with these enzymes.
