If a particular stretch of DNA has the base sequence TAC, what will be the base sequence of the anticodon of the tRNA that carries the amino acid encoded by that stretch of DNA?
A)TAC
B)UAC
C)ATG
D)GUC

Question

Quizplus · Accepted Answer

The anticodon of the tRNA that carries the amino acid encoded by the stretch of DNA TAC will be complementary to it. Therefore, the anticodon will have the base sequence AUG. However, RNA contains uracil (U) instead of thymine (T), so the actual anticodon will be UAC. So the best choice is B.
