|
What protein transcribes DNA into RNA?
|
DNA dependent RNA polymerase
|
|
|
What are the phases of polymerase activity?
|
Binding of polymerase to DNA promoter, Initiation, elongation, and termination
|
|
|
What is the side of the DNA strand that is read called?
|
The template strand.
|
|
|
In bacteria, what must bind to RNA polymerase to cause it to bind to DNA?
|
A sigma subunit.
|
|
|
When does the sigma subunit come off of the RNA polymerase?
|
After it has passed the promoter sequence.
|
|
|
What is the "power switch" for polymerase?
|
cAMP receptor protein (CRP)
|
|
|
Which strand will have the same sequence as mRNA?
|
The non-template strand.
|
|
|
In a eukariot cell what is the starting point for a gene sequence?
|
The TATA box (is useful because it is easier to pull apart there).
|
|
|
How does exonuclear mRNA avoid being broken up?
|
It has a cap placed on the 5' end.
|
|
|
What is an mRNA sequence called with all of its introns removed?
|
Mature RNA.
|
|
|
What does a reverse transcriptor do?
|
Makes a DNA strand from RNA (how a retrovirus works to insert it's own DNA into a host's DNA).
