Explanation:
The sequence of coding strand is same as RNA except thymine at the place of uracil.

If both the strands copied during transcription, then what will happen?
1 The segment of DNA would be coding for two different proteins
2 Two RNA will be produced simultaneously complementory to each other.
3 There will be formation of double helical RNA
4 All of the above
Explanation:
First, if both strands act as a template, they would code for RNA molecule with different sequences (Remember complementarity does not mean identical), and in turn, if they code for proteins, the sequence of amino acids in the proteins would be different. Hence, one segment of the DNA would be coding for two different proteins, and this would complicate the genetic information transfer machinery. Second, the two RNA molecules if produced simultaneously would be complementary to each other, hence would form a double stranded RNA. This would prevent RNA from being translated into protein and the exercise of transcription would become a futile one.
