Question
Which tRNA can bind at mRNA codon UGA?
A. tRNA with anticodon ACU ⃝
B. tRNA with anticodon ACT
C. tRNA with anticodon TGA ⃝
D. tRNA with anticodon TC
Solution
The correct answer is A. tRNA with anticodon ACU.
Here's the step by step explanation:
-
The mRNA codon mentioned in the question is UGA.
-
In the process of translation, tRNA molecules carry amino acids to the mRNA to be assembled into proteins. Each tRNA has an anticodon that is complementary to an mRNA codon.
-
The rules of base pairing are: A pairs with U, and C pairs with G in RNA.
-
Therefore, the tRNA anticodon that can bind to the mRNA codon UGA is ACU.
So, option A is the correct answer.
