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 tell 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' means one lot of letters go next to another.
'not' suggests deleting specific letters.
'right' becomes 'r' (common abbreviation).
'conceit' after 'greed' is 'greedconceit'.
'greedconceit' with 'r' removed is 'geedconceit'.
'geedconceit' with letters rearranged gives 'GENETIC CODE'.
Can you help me to learn more?
(Another definition for genetic code that I've seen is " DNA data framework".)
