Answer:
In DNA replication for a TTACG sequence the complementary strand would have the AATGC sequence.
Step-by-step explanation:
DNA replication is the production of a new strand from an existing strand. The order of the sequence of nitrogenous bases of the new strand is complementary to the original base sequence, taking into account the complementarity of bases, where a purine binds to a pyrimidine:
Accordingly, if the sequence on the original strand is TTACG, the sequence on the new complementary strand is AATGC.
