The right answer is A DNA template is used to create an mRNA strand.
In molecular biology, transcription is a mechanism for "copying" gene data, which allows their use to create biological material by assembling amino acids into proteins according to the genetic code.
It takes place in the nucleus of cells (in eukaryotes) and consists in copying so-called coding regions of DNA to transcribe them into RNA molecules. Indeed, if the DNA molecule is the universal carrier of genetic information, it is the messenger RNA molecules that are recognized by the protein sequence translation machinery. Through messenger RNA, the cell will be able to express the genetic information contained in its genes and to make the necessary proteins for its functioning.
The enzyme that catalyzes this transcription reaction is called RNA polymerase.
