Kernels camouflaged in clue (6)
I believe the answer is:
nuclei
'kernels' is the definition.
(I've seen this before)
'camouflaged in clue' is the wordplay.
'in clue' anagrams to 'NUCLEI'.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for nuclei that I've seen before include "masses, at the core" , "Cores of atoms" , "Central pieces" , "Central parts of atoms" , "Kernels" .)
