Operator (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 operā ( rī ) (to work, effect).

Hydronephrosis and Hydroureter To distinguish acute and chronic hydronephrosis, one may consider acute as hydronephrosis that, when corrected, allows full recovery of renal function.

operator In addition to these operators, many programs and programming languages recognize other operators that allow you to manipulate numbers and text in more sophisticated ways. For example, Boolean operators enable you to test the truth or falsity of conditions, and relational operators let you compare one value to another. (2) A computer operator is an individual who is responsible for mounting tapes and disks, making backups, and generally ensuring that a computer runs properly.
