  • During the experiment, scientists observed derepression that activated previously silent genetic pathways.

Examples

  • As Figure 8A shows, in a put3D mutant, LEU1 and LEU2 are also derepressed, and as for BAT1, this derepression is Leu3 dependent.

Morphology

derepression = repression (semi-transparent) = de + repress + ion

The meaning is largely 'removal of repression', but the gene-regulation sense is specialized scientific usage.

Etymology

The word derepression comes from the prefix de- meaning 'remove' and press meaning 'to press down', the same root you see in pressure. In genetics, derepression is like lifting the 'press' or block on a gene so it can become active.
