Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If mRNA has a codon CAU, what is the corresponding anticodon on the tRNA molecule?
A
CAT
B
GUA
C
CAU
D
GTA
Explanation: 

Detailed explanation-1: -The anticodon of L. plantarum tRNAIle2(CAU) is modified by TilS. In most eubacteria, the anticodon of tRNAIle2(CAU) is modified by TilS after transcription. The L modification of the anticodon loop is required for recognition by IleRS and for decoding of AUA codon (16).

Detailed explanation-2: -For instance, a messenger RNA codon GCA matches with the transfer RNA with the anticodon CGU, which carries with it the amino acid called alanine. That alanine is then added to the growing protein chain.

Detailed explanation-3: -Answer and Explanation: If the anticodon on a tRNA is 5’ GUA 3’ the codon is 3’ UAC 5’. The 5’ GUA 3’ anticodon is complementary to the 3’ UAC 5’ codon. the mRNA codon UAC codes for Tyrosine.
