Probe into criminal intercepting personal ID (7,11)
I think it could be either:
genetic fingerprint
'personal id' is the definition.
(DNA that can identify a person)
'probe into criminal intercepting' is the wordplay.
'probe' becomes 'finger' (finger can mean to poke or probe).
'into' is an insertion indicator.
'criminal' is an anagram indicator.
'intercepting' with letters rearranged gives 'geneticprint'.
'finger' going inside 'geneticprint' is 'GENETIC FINGERPRINT'.
(Another definition for genetic fingerprint that I've seen is " Individual's specific DNA configuration".)
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for genetic that I've seen before include "- - code (biol.)" , "Relating to heredity" , "coming from a common source" , "Passed down from a previous generation" , "Tending to occur among members of a family usually by heredity" .)
