By DNA code, you may mean the genetic code - the translation of nucleotide triplet codons to amino acids. Or you may mean the DNA sequence in general.

Squids very clearly evolved within the cephalopods, and there is strong molecular and anatomical support for this. Squids did not evolve separately early on in the history of life.

I specifically meant the condon sequences but they also share conserved sequences with other forms of life so both interpretations are actually true.

Yeah, they fit in on all levels. They use the universal genetic code. They're eukaryotes with mitochondria. They're cephalopods along with octopuses and cuttlefish.
