Are several proteins involved in DNA replication

Several enzymes are needed for DNA replication. As enzymes are proteins hence, it can be said that many proteins are needed for the replication of DNA.

Some of them are:

Helicases are required for unwinding the DNA.

Topoisomerases are required for unwinding the supercoiling of the DNA.

Ligases are proteins or enzymes which join the nucleotides to make up a strand.

DNA polymerases are involved in synthesizing the new strand of DNA.
