Basal apparatus = RNAP II +
general TF's
most have Inr = Py2APy5 with A at startpoint
TATA box at -25
TATA box bound by TBP, part of the factor TFIID
along with other TAF's.  TBP is found associated
with the other RNA polymerases as well.  TBP
binds to the minor groove, like nucleosomes.  A
series of TAF's bind and are followed by RNAP.
Most of the TAF's must be released before
elongation can start.
