ligase
Scientists use an enzyme called restriction enzyme to cut genes out of strands of DNA.
The enzyme that separates the two strands of DNA to start the replication process is called helicase.
Assuming this is regarding DNA replication or transcription, the enzyme helicase separates the two strands.
Topoisomerase is the enzyme that unwinds the DNA during replication. It binds to the DNA, and separates the double strands and form a replication fork. After which the primer bind to the start site, and DNA polymerase starts DNA synthesis.
DNA ligase
DNA polymerase
The enzyme
RNA polymerase is the enzyme that binds to the DNA promoter region and separates the DNA strands during transcription. It then synthesizes an mRNA molecule using one of the strands as a template.
the enzyme Lactase will enclose the single strands of DNA
DNA helicase is the enzyme that aids DNA in unzipping during transcription.
In humans, many enzymes are involved in DNA replication. Among them are: DNA polymerase I DNA polymerase III Ligase Primase Helicase DNA polymerase I and III perform the bulk of the actual reproduction--their job is to add nucleotides to the growing strands. The others perform specialized functions and are essential to the process.
