Molecular Basis of Inheritance

Which one is the correct product of DNA-dependent RNA polymerase on the given template?

3′-TACATGGCAAATATCCATTCA-5′

  1. A.5′-AUGUAAAGUUUAUAGGUAAGU-3′
  2. B.5′-AUGUACCGUUUAUAGGGAAGU-3′
  3. C.5′-ATGTACCGTTTATAGGTAAGT-3′
  4. D.5′-AUGUACCGUUUAUAGGUAAGU-3′✓

Solution

RNA polymerase reads the template 3′→5′ and builds a complementary RNA 5′→3′ with U in place of T: 3′-TACATGGCAAATATCCATTCA-5′ gives 5′-AUGUACCGUUUAUAGGUAAGU-3′.
