Match General Transcription Factors with their functions;

i. TAFs	A. Appears to regulate the binding of TBP to DNA. It does this using an inhibitory flap that binds to the DNA-binding surface of TBP, another example of molecular mimicry. This flap must be displaced for TBP to bind TATA.
ii. TFIIB	B. Insert into the RNA-exit channel and active center cleft of Pol II in a manner analogous to the sigma region 3/4 linker in the bacterial case.
iii. TFIIH	C.  As an ATP-driven translocator of double-stranded DNA.
iv. TFIIF	D. This two-subunit (in humans) factor associates with Pol II and is recruited to the promoter together with that enzyme.
