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

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)

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
