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.
Ligase here means the reconnection or more specifically the re-splicing together of Dna 'fragments'. Dna ligase's role in Dna replication is to reconnect the Okazaki fragments â¦ that are created by the pattern of replication that takes place upon the COMPLEMENTARY 5'-3' strand of DNA.NA helicase unzip, or separate, a strand of DNA at positions  called origins. This means that the hydrogen bonds between  complementary base pairs are removed (DNA is dou â¦ ble stranded!).  When they separate double-stranded DNA into single strands, it  allows each strand to be copied (replication).
