Unit 2-Lecture 10 Flashcards
1
Q
Transcription
A
DNA dependent RNA polymerization
2
Q
How does RNA polymerase know where to start transcription?
A
Promoter
3
Q
Promoter
A
Piece of DNA sequence that determines:
1. where to start transcription/which direction
2. Which DNA strand is the template
3. How many copies of RNA per unit of time
4
Q
Transcription start site (TSS)
A
Where RNA polymerase adds first nucleotide
-denoted as (+1), everything to the left of the TSS is negative
5
Q
Upstream (-)
A
Everything to the left of the TSS, includes the promoter
6
Q
Downstream (+)
A
Includes TSS and everything to the right as well
