Question

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC A. UACCGUGGAAUG B. CATTCCACGGTA C. AUGGCACCUUAC D. CAUUCCACGGUA

Answer 1

Step-by-step explanation:

In a DNA molecule, Adenine forms hydrogen bonds with Thymine and Cytosine forms hydrogen bomds with Guanine.

However in mRNA, Thymine becomes Uracil (T => U)

Therefore every A in the DNA sequence becomes U,

every T in the DNA sequence becomes A,

every C in the DNA sequence becomes G,

every G in the DNA sequence becomes C.

The answer is A.
