Question

Given the base sequence AGCTTCGATCG on a DNA strand, what is the base sequence of the complementary DNA strand?

Answer 1

The complementary bases come in pairs:

A (adenine) - T (thymine)

G (guanine) - C (cytosine)

So....

A G C T T C G A T C G

T C G A A G C T A G C

Hope this helps! Please correct me if I'm wrong :)
