What is "transcriptome"

n. (context biochemistry genetics English) The complete set of messenger RNA molecules (transcripts) produced in a cell or a population of cells.

The transcriptome is the set of all messenger RNA molecules in one cell or a population of cells. It differs from the exome in that it includes only those RNA molecules found in a specified cell population, and usually includes the amount or concentration of each RNA molecule in addition to the molecular identities.
