what is the role of dna helicase in the replication of dna
Opening the button gives a little room, but not enough for you to get into the jeans. You then pull down the zipper, which opens the jeans up even more, giving you the space you need to get into them. This is very similar to the role that DNA helicase plays in DNA replication: DNA helicase is the zipper. It unzips our DNA strands to allow space for attachment and to expose the nucleotides that are used as a template during DNA replication and transcription.
