Answer
Because the two strands of DNA are complementary, the mrNA of a given gene can be synthesized using either strand as a template.
Incorrect.
Work Step by Step
DNA:
Strand 1: AGG
Strand 2: TCC
If we used Strand 1 as the coding (sense) strand, mRNA: UCC (translates into Ser)
If we used Strand 2 as the coding (sense) strand, mRNA: AGG (translates into Arg)
Since the mRNA of a given gene is very specific and it needs the amino acid Arg, so we transcribed Strand 2 from the DNA into mRNA which will give us AGG and eventually Arg. If we transcribed Strand 1, then we would have Ser which would be an incorrect amino acid according to the gene.
