The National Center for Biotechnology Information at the US National Institutes of Health (NIH) defines gene expression as "the phenotypic manifestation of a gene or genes by the processes of genetic transcription and genetic translation."[1] Gene expression takes place in two stages. The first is transcription: the base sequence on DNA is copied to a molecule of mRNA. Next, translation: the mRNA molecule leaves the cell nucleus for the cytoplasm and specifies the particular amino acids that will make up individual proteins in the process of protein synthesis.[1]
Gene expression analysis examines patterns of gene expression in transcription, whether under specific conditions or in certain kinds of cells.[1]
