In eukaryotes, the anticodon of tRNA that pairs with the start codon of mRNA during translation is (1) UAA (2) UCA (3) UAC (4) UUU
In eukaryotes, the anticodon of tRNA that pairs with the start codon of mRNA during translation is (1) UAA (2) UCA (3) UAC (4) UUU

Correct option:(3) UAC
Solution:

  • In eukaryotes, initial codon on m-RNA is
    AUG. During translation, t-RNA, anticodons are exactly complementary to m-RNA.
  • Hence anticodon will be UAC.
  • [A = U, U = A, C ≡ G]
