Answer:
The correct answer will be- T A G C A T.
Step-by-step explanation:
The mRNA is the messenger molecule formed by the process of transcription from the anti-sense DNA strand as a template.
The mRNA usually contains code for the synthesis of proteins but can also synthesize the DNA by the process of reverse transcription. The complementary nucleotide will bind according to the Chargaff rule which states that A will bind T or U and G will bind C.
So, if mRNA strand is- A U C G U A
DNA strand will be- T A G C A T.
