Informational rna

Definition

noun

A type of RNA that carries the code or chemical blueprint for a specific protein. In the early stages of protein synthesis, the mRNA is synthesized from a DNA template during transcription.


Supplement

The informational RNA or messenger RNA (mRNA) is one of the three types of RNA; the other two are transfer RNA (tRNA) and ribosomal RNA (rRNA).

In eukaryotes, the mRNA carries the genetic information from the nucleus to the site of protein synthesis (ribosome) in the cytoplasm to be translated. In non-eukaryotes such as bacteria, the mRNA is produced and translated in the cytoplasm of the bacterial cell.

Mg/Ca advice

a relationship between magnesium and calcium? Kind of a strange question. Generally calcium is used by cells as a second messenger, with an informational role. Magnesium, on the other hand, is generally used as a cofactor for some enzymes.
