Explanation:
Detailed explanation-1: -Complementary sequence: Nucleic acid sequence of bases that can form a double-stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.
Detailed explanation-2: -The base pairs on one strand of the DNA bind with the base pairs of the other strand specifically. A always pairs with T with two hydrogen bonds and G always pairs with C with three hydrogen bonds. So if one strand is ATGCTTGA then the complementary strand will be TACGAACT.
