Morphology

restriction + enzyme

The compound is partially compositional: a B1 learner who knows 'restriction' (a limit) and 'enzyme' (a protein catalyst) can infer it denotes an enzyme related to 'restriction' or limiting activity. However, the precise, technical sense — an enzyme that cuts DNA at specific sequences — is domain-specific and not directly derivable from the common meanings, so the relation is only partially predictable.

Etymology

Restriction enzyme comes from bacteria that make an enzyme to restrict invading viruses by cutting their DNA at certain spots. Scientists used that image—an enzyme that cuts DNA at specific places—so today restriction enzymes are the tools we use to cut DNA in genetic research.
