Question

If one strand of DNA has the sequence ATGCTTGA, the sequence in the complementary strand would be (A) TCCGAACT (B) TACGTACT (C) TACGAACT (D) TAGCTAGT

Tardigrade Admin · Accepted Answer

In DNA, adenine (A) and thymine (T) are joined by two hydrogen bonds while guanine (G) and cytosine (C) are joined by three hydrogen bonds. No other combination of four bases is possible. Hence, the sequence of complementary strand is TACGAACT.
