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