Answer

TTTGCGAA

Explanation

Every molecule of DNA is a double helix which is formed from two complementary strands of nucleotides. Hydrogen bonding between A-T and G-C is responsible for holding these complementary strands. Nucleic acid sequences of bases which forms the double-stranded structure of DNA by matching the base pairs are called complementary sequences. Where these complementary sequences are C-A-T-G which is complimentary to G-T-A-C.
