Question

The diagram given below shows a segment of DNA that codes for the enzyme pepsin. Anita used strand (b) for making mRNA to translate the enzyme pepsin. Even after repeated attempts, she could not create the enzyme.

Answer 1

Anita used strand (b) to make mRNA. Since strand (b) is complementary to the coding strand, it produced incorrect mRNA, so the enzyme pepsin could not be formed. She should have used strand (a) to make the correct mRNA for proper enzyme production.
