If the dna code were attcgataca, what would be the code when replicated

It depends on how you need to replicate it - to mRNA or into another DNA strand.

If in mRNA, don't forget that Thymine does not exist and it would be Uracil instead. The strand into mRNA is:

UAAGCUAUGU

If into another DNA strand, then you would just change them into their opposing ( Adenine to Thymine and Cytanin to Guanine and vice versa ) 

TAAGCTATGT

Hope this helps!
