A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is
A) 3' UCA 5'.
B) 3' UGA 5'.
C) 5' TCA 3'.
D) 3' ACU 5'.
E) either UCA or TCA, depending on wobble in the first base.

Question

Quizplus · Accepted Answer

The triplet code AGT corresponds to the mRNA codon UCA. The direction of transcription and translation are opposite to each other, so the 5' end of the DNA strand corresponds to the 3' end of the mRNA codon. Thus, the correct answer is (A) 3' UCA 5'.
