Which statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA?
A. The enzyme binds to a sequence of nucleotides called introns that are cut out before they become functional.
B. The enzyme proofreads each DNA strand to help ensure each molecule is copied exactly in the order of the original strand.
C. The enzyme splices exons together before transcription begins to form the final mRNA molecule.
D. The enzyme only binds to regions of DNA known as promoters, which have specific base sequences.

"The enzyme only binds to regions of DNA known as promoters, which have specific base sequences" statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA.

Option: D

Explanation:

Transcription is the mechanism which happens when polymerase of RNA (principal enzyme for transcription) attaches by aid proteins or personally or to a promoter segment near the gene beginning.

For generating a new molecule of RNA which is complementary, RNA polymerase utilizes one of the DNA strands or the parent strand as a template.

For an instance, trying to block mushroom toxicity transcription triggers liver failure and death, as no new RNAs and therefore no fresh proteins can be produced.

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.

explanation:

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.
