13.  If the arrangement of bases on DNA is CATTAG, then a corresponding strand of mRNA will be
a. GTAATC        b. TGCCGA         c. GUAAUC         d. UGCCGA

Note that the pairing is still complementary.  However, since an RNA molecule is being produced, the strand will have U containing bases rather than thymine containing bases.
