The homologous structures indicates divergent evolution.

Answer:GGATCGA
Explanation:
The complementary double helix of the DNA are antipararell to each other.
Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).
Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below
5' CCTAGCT 3'
3' GGATCGA 5'
