(1) (genetics) A segment of DNA where the repressor binds to, thereby preventing the transcription of certain genes. (2) (surgery) The one performing surgical procedures. (Genetics) In the Operon Model, the operator is the gene in which a repressor binds. This results in the prevention of the RNA polymerase from binding to it, thus, preventing the expression of certain genes in the operon unit. Word origin: Latin operÄ ( rÄ« ) (to work, effect).
Newton's first law states that an object at rest will stay at rest unless acted on by an unbalanced external force.. This concept is commonly referred to as inertia and was first hypothesized by Galileo Galilei in the late 1500s.
Inertia Definition:the property of any body to resist changes in its state of motion. Example: When the person gently pulls the tablecloth, the plate and cup will stay in place due to inertia. The plate and cup will resist a change in motion. Inertia Definition:the property of any body to resist changes in its state of motion.
