Abstract

Transcriptomics, a genome-wide measurement of mRNA expression levels based on DNA microarray technology is one of the prominent fields of study. This is the term given to the set of all transcripts or messenger RNA (mRNA) molecules produced in cells. It can also be applied to the specific subset of transcripts present in a particular cell or the total set of transcripts in a given organism. Transcriptomics has evolved from a variety of already present technologies and areas. These areas include proteomics, genomics, and environmental science.
