Answer #1

In eukaryotes for the replication process three main polymerases are necessary, they are DNA polymerase alpha also known as Pol α, DNA polymerase delta also known as Pol δ and DNA polymerase epsilon also known as Pol ε.

Pol α helps in the initiation of the DNA replication process. After the primer is created it helps in the formation of DNA/RNA primer and it elongates DNA up to 20 nucleotides. It acts on both lagging and leading strands.

Pol δ and Pol ε they help in further elongation, they extend the newly formed daughter DNA strand.

Pol ε also participates at the origins of DNA replication when the replication fork is established.
