Further explanation

Gene expression is a series of processes using information from a gene for the synthesis of functional gene products. These products can be proteins, as well as non-protein coding genes such as RNA transfer (tRNA) or small nucleus RNA genes (snRNA), both of which are functional RNA products.

The process of gene expression is used by all living things including eukaryotes, prokaryotes (bacteria and archaea), and is used by viruses - to produce macromolecular machines for their survival.

Several stages in the process of gene expression are transcription, splicing or RNA splicing, translation, and post-translational modification of proteins. Gene regulation provides cell control over structure and function, and is the basis for cell differentiation, morphogenesis, and the versatility and adaptability of each organism. Gene regulation can also function as a substrate for evolutionary change, because the control of the time, location, and amount of gene expression can have a large effect on the function (action) of genes in cells or in multicellular organisms.

In genetics, gene expression is the most fundamental level at which genotypes give rise to phenotypes, that is, observable traits. The genetic code stored in DNA is "interpreted" by gene expression, and the properties of that expression give rise to an organism's phenotype. Such phenotypes are often expressed by protein synthesis that controls the shape of the organism, or which acts as an enzyme that catalyzes the specific metabolic pathways that characterize the organism. Regulation of gene expression is thus essential for the development of an organism.
