DNA sequences that direct RNA polymerase to the initiation site are called .

promoters

Explanation:

Promoters are DNA sequences that direct RNA polymerase to the initiation site. Promoter sequences are simply DNA sequences that helps in defining where the gene transcription by RNA polymerase will start.

Promoter sequences are located directly upstream and are an important part of the expression vectors as the binding of DNA to the RNA polymeras are being controlled by them.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
