Identify the correct anticodon sequence on a tRNA molecule that will bind to the mRNA codon 5^ GAC 3^ during protein synthesis.
Options
- A5^ CUG 3^
- B5^ CTG 3^
- C5^ GUC 3^
- D5^ GAC 3^
Correct answer
C. 5^ GUC 3^
Step-by-step solution
The mRNA codon is given as 5^ GAC 3^ . During translation, the tRNA anticodon binds to the mRNA codon in an antiparallel and complementary manner. According to the complementary base pairing rules for RNA, G pairs with C, and A pairs with U. Therefore, the complementary sequence to the mRNA codon 5^ GAC 3^ is 3^ CUG 5^ . Writing this sequence in the standard 5^ to 3^ direction gives 5^ GUC 3^ . Answer: 5^ GUC 3^
