Answer:
3'-TTACGATG-5'
Explanation:
The DNA sequence is in couples where A is united T and G is united C, so what we do is replace in the complementary sequence the original nucleic acids, remember A-T, G-C.
5'-AATGCTAC-3'
3'-TTACGATG-5'
To remember: the DNA sequence is 5'-3' in one sequence and its complementary is inverse, what means it goes 3'-5'.
Also the T-A is united by 2 hydrogen bonds, and G-C is united by 3 hydrogen bonds.
