Question

If sequence on DNA chain is ATG CAT TGC ATG correct sequence on m-RNA?

• A. UAC GUA ACG UAC
• B. TAC GTA CGT ACG TAC
• C. UAC GTA CGU ACG TAC
• D. TAC GUA CGU ACC UAC

Answer 1

The correct option is A UAC GUA ACG UAC

In DNA the bases are adenine(A), guanine(G), cytosine(C) and thymine(T). An always pairs with T and G always pairs with C. In RNA the bases are adenine(A), guanine(G), cytosine(C) and uracil(U). An always pairs with U and G always pairs with C. Thus, the correct sequence on m-RNA is UAC GUA ACG UAC.

Hence, the correct answer is option A.
