Morphology

noncognate = cognate (semi-transparent) = non + cognate

Formally 'non-' + 'cognate' yields 'not cognate', but this sense is technical (biochemistry/biology) and may be opaque to general learners.

Etymology

The word noncognate is built from the beginning non- meaning 'not' and cognate meaning 'related' or 'matching'. So, in biology and chemistry, a noncognate molecule is one that is not the usual or matching partner for a protein or enzyme.
