If the nucleotide or base sequence of the DNA strand used as a template for messenger RNA synthesis is ACGTT, then what would be the sequence of bases in the corresponding mRNA?
A) GUACC
B) ACGTT
C) UGCAA
D) TGCAA

Question

Quizplus · Accepted Answer

When transcribing DNA to RNA, A pairs with U and T pairs with A. Therefore, the mRNA sequence would be UGCAA (the complementary base pairing of ACGTT). Choice A is incorrect because it is not the complementary base sequence to ACGTT. Choice B is also incorrect as it is simply the original DNA template strand. Choice D is incorrect because it substitutes a T for the A in the DNA template, which is not correct because RNA uses U instead of T. Therefore, the correct answer is C.
