Solution

The correct option is A 5’ GGGCAAUAAUCCG 3’

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.

In transcription two strands of DNA work separately, out of the two strands, one strand acts as template strand or non- coding strand whereas the other strand acts as a coding strand.

When template strand is used for the synthesis of RNA strand it will have a sequence complementary to that of template strand. But in the case of coding strand, the RNA will have the same base pair sequence as that of coding strand. Only instead of thymine, uracil should be there in the RNA strand.

Thus the resultant strand will have a GGGCAAUAAUCCG sequence.
