  • And these are regions called enhancers that somehow control the extent to which the gene is is switched on or off.

Morphology

enhancer = enhance (semi-transparent) = enhance + er

Formally 'enhance' + '-er' is clear, but the biological sense refers to a specialized DNA element, so the specific technical referent may not be deducible by an average B1 learner.

Etymology

Enhancer comes from the verb enhance, made from en- 'make' plus a root that means 'high', the same idea as the English word high. So in biology an enhancer 'raises' a gene's activity, which helps you remember that it makes the gene work more.
