    If one strand of a DNA has the sequence -ATGCTTCA-what is the sequence of the bases in the complementary strand?

    Answer:

                    We know that in DNA molecule, adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G). Thus, Sequence of bases in one strand :                                     A T G C T T C A \[\therefore \] Sequence of bases in the complementary strand :         T A C G A A G T Thus, the sequence of bases in the complementary strand is TACGAAGT.
