Rut element

Explanation:

Promoters are the sequences that serve as a binding site for RNA polymerase and regulate the transcription of the adjacent gene. Bacterial promoters have some conserved sequences. Two of these sequences are present at -10 and -35 positions and serve as an interaction site for the sigma subunit of RNA polymerase holoenzyme. The consensus sequence at -10 position is (5')TATAAT(3') and the consensus sequence at the -35 region is (5')TTGACA(3').

The UP element, upstream promoter element is an AT-rich sequence present between -40 and -60 positions in the promoters of some genes. The UP elements also serve as a binding site for the sigma subunit of RNA polymerase. The promoter sequence present on the downstream side of the -10 element is called the discriminator sequence.

The rho-dependent terminators use a CA-rich sequence called a rut (rho utilization) element. The sequence serves as a binding site for rho protein during termination.
