Transcription is when RNA is made from DNA. During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed. This process is similar in eukaryotes and prokaryotes.s in DNA, mRNA genetic information is in the sequence of nucleotides, which are arranged into codons consisting of three bases each. Each codon encodes for a specific amino acid, except the stop codons, which terminate protein synthesis.
The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA. Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand.There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA.igure 2: RNA polymerase (green) synthesizes a strand of RNA that is complementary to the DNA template strand below it. Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription.
