If a strand of mRNA has the sequence 5ʹ-CUGUCA...ACUC-3ʹ (with […] representing the intervening sequence), what was the template strand of DNA used to produce this mRNA?
A) 5ʹ-CUGUCA...ACUC-3ʹ
B) 5ʹ-CTGTCA...ACTC-3ʹ
C) 3ʹ-CTGTCA...ACTC-5ʹ
D) 3ʹ-GACAGU...UGAG-5ʹ
E) 3ʹ-GACAGT...TGAG-5ʹ

Quizplus · Accepted Answer

The template strand of DNA is complementary to the mRNA strand. The mRNA sequence 5ʹ-CUGUCA...ACUC-3ʹ pairs with the DNA template strand 3ʹ-GACAGT...TGAG-5ʹ, where RNA uses uracil (U) instead of thymine (T).
