What does RNA Polymerase do?
Makes a strand of DNA from the template
Determines where transcription starts
Makes a strand of RNA from the template
Translates mRNA into a protein
What do transcription factors do?
Help guide RNA polymerase to the transcription start site
Regulate how much of an mRNA is made
Turn on or off transcription
Makes a strand of RNA from a DNA template
Ensure RNA polymerase functions normally
Which end of the RNA molecule (5' or 3') can additional bases be added to?
(a)
Why can bases only be added to one end of the RNA?
the 3' carbon is free to make a bond
the 5' carbon is free to make a bond
the 3' carbon is already bound to the previous base in the chain
Transcribe this DNA sequence to an mRNA:
3' TAGCATG 5'
3' ATCGTAC 5'
5' AUCGUAC 3'
3' AUCGUAC 5'
5' ATCGTAC 3'
Transcribe this DNA sequence into an mRNA:
5' ATGGCTGA 3'
(a)
mRNA sequences are typically written in the (a) direction
