In multicellular organisms, regulatory sequences can spread thousands of nucleotides from the promoter—both upstream and downstream—and can be made up of tens of regulator binding sites. Often, these binding sites are grouped in units called_?

Termination is a normal and important function at the ends of genes. There, sequences called terminators trigger the elongating polymerase to dissociate from the DNA and release the RNA chain it has made, In bacteria, terminators come in two types: Rho-dependent and Rho-independent, choose correct statements about this;

Rho-dependent	a- rut sites
	b- has an ATPase activity
Rho-independent	c- terminates only those transcripts still being transcribed beyond the end of a gene or operon
	d- intrinsic terminator

Most recent experiments suggest that the last of these is at least an important part of the story and that the conformational change causes the elongating complex to stall, with dissociation following more slowly- this conformational change caused by,
