I wanted to ask about the enzymes that work in transcription. So obviously at the start, the DNA helix is 'unzipped'. Is the enzyme that does this DNA helicase?? and when the strands join back up, is that done by DNA polymerase or are these 2 enzymes only for DNA replication?
Thank you!
Thank you!

There’s also DNA gyrase which uncoils the DNA strand and DNA ligase which joins the fragments of the antilagging strand. They’re also the ones you need to know for OCRA

Ah okay, what does that do during transcription? I struggle grasping this unit for some reason

Transcription is about the synthesis of mRNA
This involves RNA polymerase II in eukaroytes. It does a lot! It basically interacts with transcription factors to pry apart DNA and then synthesises the mRNA transcript. It also does proofreading of the mRNA to ensure the right sequence is incorporated
I cant remember much sorry. This is off the top of ma head
