#Unit 3. Fundamental Processes

TRCF binds to double-stranded DNA upstream of the polymerase and uses the ATPase motor to translocate along the DNA until it encounters the stalled RNA polymerase.

Rho-independent terminators, also called intrinsic terminators because they need no other factors to work, consist of two sequence elements: a short-inverted repeat (of 20 nucleotides) followed by a stretch of about eight A:T base pairs.
