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
