Quick Answer. Helicase is an enzyme that unwinds DNA strands. After it unwinds double-stranded DNA, two pairs of single-stranded DNA are available for replication, transcription and translation.
Helicase, made of six proteins arranged in a ring shape, unwinds the DNA double helix into two individual strands. Single-strand binding proteins, or SSBs, are tetramers that coat the single-stranded DNA.This prevents the DNA strands from reannealing to form double-stranded DNA.Primase is an RNA polymerase that synthesizes the short RNA primers needed to start the strand replication process. DNA polymerase is a hand-shaped enzyme that strings nucleotides together to form a DNA strand.his prevents the DNA strands from reannealing to form double-stranded DNA.
