Explanation / Answer

The answer is

Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting.

The enzymes and its roles

Helicase - Melts the DNA or unzips the DNA

Primase - Synthesizes the primer

DNA Polymease - Main enzyme in DNA replicaiton, synthesizes DNA.

Ligase - attahes one DNA with another especially in lagging strand.

SSB - It binds to single standard DNA molecules and prevents the reuniting.
