Prokaryotic Transcription Flashcards
1
Q
Promoter
A
a DNA sequence at which RNA polymerase may bind, leading to initiation of transcription
2
Q
-35 site
A
part of the promoter in DNA
3
Q
-10 site
A
part of the promoter in DNA
4
Q
+1 site
A
site of transcription start
5
Q
UP element
A
an upstream element that facilitates or stops transcription from occurring
6
Q
Sigma Factor
A
a transient subunit of the bacterial RNA pol that directs the enzyme to the promoter
different sigma factors are specific for different promoters
7
Q
RNA Pol
A
an enzyme that catalyzes the formation of RNA using a strand of DNA as a template
8
Q
Rho Dependent Termination
A
helicase catches up when RNA pol pauses at specific sequences
9
Q
Rho Independent Termination
A
inverted repeats form stem loop/hairpin formation follows by repeat uracils
