Answer:
In transcription, the mRNA strand is formed by complementary base pairing of the template DNA strand. However we should note that the nitrogenous bases in mRNA are Adenine, Guanine, Cytosine and Uracil, while those in DNA are Adenine, Guanine, Cytosine and Thymine.
So the mRNA strand would be formed by matching the A in DNA with U in mRNA, T in DNA with A in mRNA, C in DNA with G in mRNA and G in DNA with C in mRNA.
