Examples
-
A repressor is a protein product made by one gene in the bacterium in order to control a second gene by turning it off when its product is not wanted.
-
This control function had been defined genetically by the work of Jacob and Monod, but a repressor is made in such small amounts that it was an extraordinarily elusive biochemical entity.
-
The repressor is produced by a regulator gene and acts on an operator gene.
-
Now, then, the repressor is responsible for immunity.
-
The reason for this, the scientists discovered, is that a protein called a repressor molecule attaches itself to the DNA site where the copying into RNA begins, thus blocking off the DNA and preventing the gene from producing the RNA responsible for the synthesis of the enzyme.
