A particular triplet of bases in the template strand of DNA is AGT. The anticodon of the tRNA when the triplet bases are translated is...?

Question

a. UGA.

b. AGU

c. TCA.

d. AGT.

Answer 1

The template strand is the coding strand, otherwise known as the antisense strand. If we were to assign directionality to this sequence, we could write 5'-AGT-3' for learning purposes. The resulting mRNA would be 3'-UCA-5'. The tRNA is complimentary and antiparallel to the mRNA so the tRNA would read 5'-AGU-3'. Thus, the answer is B.
