Which of the following statements about transcription is correct?
During elongation, the RNA strand is extended in the 5' to 3' direction.
How is a mutation in a bacterial cell that deletes three base pairs 10 base pairs upstream from the +1 site likely to affect transcription and why?
Initiation will be inhibited because sigma cannot bind to the promoter.
Why are ribonucleoside triphosphates the monomers required for RNA synthesis rather than ribonucleoside monophosphates?
Ribonucleoside triphosphates have high potential energy, making the polymerization reaction exergonic.
During transcription, in which direction is (1) RNA synthesized and in which direction is (2) the DNA template "read"?
A promoter is ______.
a sequence in DNA that brings RNA polymerase near the site for transcription
(a) Add another OH to the sugar.
(b) Remove a CH3 group from the base.
