  4. DUGA.UUV.UGG

Correct answer

A. AUG.UGA.UUU

Step-by-step solution

Among the given options, only first one can be transcripted because it possesses an initiation codon-AUG which codes for methionine. Rest of the mRNA sequences start with termination codons, i.e. UAA (Ochre), UAG (Amber) and UGA (Opal). Therefore, these cannot be transcripted.
