If one strand of DNA had a base sequence of ATTGCA what base

If one strand of DNA had a base sequence of A-T-T-G-C-A, what base order would be found on the complementary strand of DNA. G-C-C-A T-A-A-C-G-T C-G-G-T-A-C A-T-T-G-C-A

Solution

3ATTGCA5

5TAACGT3

the base sequence of the complementary strand would be TAACGT.

A binds to T and vice versa.

G binds to C and vice versa
