Messenger 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 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.

How does a cell know how big it is?

... Feedback loops seem logical... This is based on that when you culture something in a petri dish, it will stop growing, like e. coli. The chemical messenger that tells cells that there is no room and they need to stop dividing, in this case, is cAMP. Based on that, I would think that it is similar ...
