Question

Quizplus · Accepted Answer

The mRNA strand produced during transcription has the same polarity as the nontemplate (also known as the coding or sense) strand of DNA. This is because the mRNA is synthesized in a 5' to 3' direction, complementary to the 3' to 5' template strand, making it identical in sequence (except for the substitution of uracil for thymine) to the nontemplate strand.
