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." 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.
Gene expression analysis examines patterns of gene expression in transcription, whether under specific conditions or in certain kinds of cells.
