Gene expression: it is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as transfer RNA or small nuclear RNA genes, the product is a functional RNA. The process of gene expression is used by all known life eukaryotes , prokaryotes , and utilized by viruses to generate the macromolecular machinery for life.Several steps in the gene expression process may be modulated, includi...
