messenger RNA

n. Abbr. mRNA
The form of RNA that mediates the transfer of genetic information from the cell nucleus to ribosomes in the cytoplasm, where it serves as a template for protein synthesis. It is synthesized from a DNA template during the process of transcription.

messenger RNA

n
(Biochemistry) biochem a form of RNA, transcribed from a single strand of DNA, that carries genetic information required for protein synthesis from DNA to the ribosomes. Sometimes shortened to: mRNA See also transfer RNA, genetic code

messenger RNA


n.
a molecule of RNA that is synthesized in the nucleus from a DNA template and then enters the cytoplasm, where its genetic code specifies the amino acid sequence for protein synthesis. Abbr.: mRNA

This process has the characteristics of a nested transcript and when this transcription is done on one gene, it is known as monocistronic translation.
In the well-studied asexual blood stages, cyclic monocistronic gene activation occurs at the transcriptional level; however, relatively few transcription factors have been identified, thus other types of regulatory processes that contribute to this coordinated gene expression are believed to exist.
This is not possible in eukaryotes because only the AUG site nearest the 5' terminus of the mRNA can be used to initiate polypeptide synthesis; thus eukaryotic mRNA is monocistronic.
