Answer:
AACTGATCCGAT
Explanation:
As per the Chargaff's rule , there is a rule of binding of four base molecules of DNA
The amount of adenine is approximately equal to the amount of thymine and hence it can be concluded that adenine binds with the thymine. Likewise the amount of guanine is equal to the amount of cytosine, hence it can be concluded that guanine binds with the cytosine.
Based on the above base pairing rule, the complementary strand for TTGACTAGGCTA would be
AACTGATCCGAT
