what does the enzyme Helicase do in BOTH RNA and DNA? and what are the differences...
Homework Answers
The Helicase is an enzyme that breaks the hydrogen bonds present between the nucleotides. In DNA helicase acts during replication and also during transcription to open up the double helix of DNA by breaking the hydrogen bonds between the nucleotides. In RNA, helicase acts by breaking the bonds between self annealed RNA.
If any queries, kindly comment before giving a thumbs up. Thank you
