TATA boxes are required for RNAP docking
True False
|
TATA boxes are required for RNAP docking
True False - there are TATA-less promoters, TATA is mostly for eukaryotes only |
|
|
RNAP I and RNAP II sequences are both generally well conserved between species
True False
|
RNAP I and RNAP II sequences are both generally well conserved between organisms.
True False - RNAP I is not well conserved |
|
|
The core element and the UPE appear to be the most important promoter elements in the promoter region for RNAP I.
True False |
The core element and the UPE appear to be the most important promoter elements in the promoter region.
True False
however, UPE absence still triggers basal transcription |

|
Which one of these is not a step of RNAP binding?
a) TBP recognizes TATA box, TFIID is recruited along with TBP b) TFIIA and TFIIB is recruited c) RNAP II recruits TFIIF d) TFIIH melts DNA by binding downstream of RNAPII and also phosphorylates tail e) These are all correct

If a CAAT isn't a HAT then Enhancers are promoters?
True False |
If a CAAT isn't a HAT then Enhancers are promoter elementers?
True False - no but enhancers are similar and contain similar elements |
