What is "mrna"

Usage examples of "mrna".

If DNA is the set of master blueprints a cell uses to construct proteins, then mRNA is like the copy of part of the blueprint that a contractor takes to the building site every day.

The system is based on thumbnail-size glass chips called microarrays that are coated with a thin layer of so-called cDNAs, which represent all the mRNAs made by a particular type of cell.

The ribosomes then translate the mRNA into the chain of amino acids that makes up the encoded protein.

The value of mRNA for research is that cells make it only when the corresponding gene is active.
