Morphology
The sense 'to reduce the expression level of a gene' is a metaphorical extension of 'knock' + 'down' (to bring something down or reduce it), so a learner could infer a general meaning of reduction. However, the specific molecular-biology usage (gene expression reduction via RNAi) is specialized and not fully predictable from the constituents alone, so prior domain exposure is needed for the precise interpretation.
Etymology
Knock down comes from the simple image of knock, meaning to hit, and down, meaning to the ground. Think of a ball hitting bowling pins and making them fall, so it means 'to hit or push someone or something so that they fall to the ground'.
