It's blueprinted in us all: a mix of conceit and greed - not right! (7,4)
I believe the answer is:
genetic code
'it's blueprinted in us all a mix' is the definition.
I can't judge whether this defines the answer.
'of conceit and greed not right' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'and' says to put letters next to each other.
'not' indicates named letters should be taken away.
'right' becomes 'r' (common abbreviation).
'conceit'+'greed'='conceitgreed'
'conceitgreed' with 'r' taken out is 'conceitgeed'.
'conceitgeed' anagrammed gives 'GENETIC CODE'.
Can you help me to learn more?
(Another definition for genetic code that I've seen is " DNA data framework".)
