A segment of DNA with the following sequence AGCTGACTATGAT is a template strand for RNA synthesis. What will be the complementary base sequence in the mRNA formed?

The correct option is B UCGACUGAUACUA

During base pairing, adenine (A) always pairs with thymine (T) in case of DNA while it pairs with uracil (U) in case of RNA. On the other hand, guanine always pairs with cytosine both in DNA and RNA.

So for the given sequence of DNA: AGCTGACTATGAT

Base sequence of mRNA will be: UCGACUGAUACUA
