RR3 Flashcards
1
Q
what is tata box
A
directs transcription at promoters of some protein coding genes
common element found upstream usually around -30
determines where rna pol starts transcribing
2
Q
name proximal cis acting elements during transcription that are active
A
Upstream tata box
TFIIB recognition element
inr initiatior
downstream promoter elements
other elements are more degenerate (not as conserved as tata box)
3
Q
what are most eukaryotic genes regulated by
A
Multiple transcriptional control elements
4
Q
describe transcriptional control elements
A
enhancers = up or downstream
tata = ~30
uas = enhancer in yeast = up to -200, sometimes downstream of start site but still affects transcription of gene
5
Q
what is cpg island promoter
A
a
