 • The extent of this transcription bubble (i.e., DNA unwinding) is constant throughout and is about 20 base pairs per polymerase molecule.

It is called as a Template strand. khushimankame10 https://padlet.com/akashkolekar217/Bookmarks/wish/775738747 2020-09-24 13:44:07 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/775738747 RNA Polymerases are enzymes that transcribe DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. RNA polymerase always builds a new RNA strand in the 5' to 3' direction i.e. it can add only RNA nucleotides (A, U, C or G) to the 3' end of the strand. khushimankame10 https://padlet.com/akashkolekar217/Bookmarks/wish/775742959 2020-09-24 13:44:58 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/775742959 In humans the main RNA polymerase does not attach instantly to promoters instead require transcription factors bind to promoter first which help the RNA polymerase to get hold on the DNA. khushimankame10 https://padlet.com/akashkolekar217/Bookmarks/wish/775748121 2020-09-24 13:46:04 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/775748121 Many eukaryotic promoters possess a sequence - TATA Box. It is recognized as one of the transcription factors. Transcription is also regulated by upstream control elements that lie 5' to the TATA box. khushimankame10 https://padlet.com/akashkolekar217/Bookmarks/wish/775753181 2020-09-24 13:47:06 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/775753181 khushimankame10 https://padlet.com/akashkolekar217/Bookmarks/wish/775946776 2020-09-24 14:25:54 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/775946776 shreya172001 https://padlet.com/akashkolekar217/Bookmarks/wish/776326288 2020-09-24 15:42:16 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/776326288 akashkolekar217 https://padlet.com/akashkolekar217/Bookmarks/wish/776716554 2020-09-24 17:02:18 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/776716554 akashkolekar217 https://padlet.com/akashkolekar217/Bookmarks/wish/776782665 2020-09-24 17:15:37 UTC https://padlet.com/akashkolekar217/Bookmarks/wish/776782665 akashkolekar217 https://padlet.com/akashkolekar217/Bookmarks/wish/776870595 RNA polymerase has associated with it an "unwindase" activity that opens the DNA helix. Topo isomerase both precedes and follows the progressing RNAP to prevent the formation of super helical complexes.
