Any concurrent set of forces, not in equilibrium, can be put into a state of equilibrium by a single force. This force is called the Equilibrant. It is equal in magnitude, opposite in sense and co-linear with the resultant. When this force is added to the force system, the sum of all of the forces is equal to zero. A non-concurrent or a parallel force system can actually be in equilibrium with respect to all of the forces, but not be in equilibrium with respect to moments.
Gene expression 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 (tRNA) or small nuclear RNA (snRNA) genes, the product is a functional RNA.he process of gene expression is used by all known life-eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses-to generate the macromolecular machinery for life.
Gene expression regulation. Definition. noun. The modulation of any of the stages of gene expression, hence, it encompasses the various systems that control and determine which genes are switched on and off, and when, how long, and to what extent the genes are expressed. Supplement.ene regulation of the lac operon of the prokaryotes was the first genetic regulatory mechanism to be elucidated. Variant: regulation of gene expression or gene regulation.
