Question
What structure of this molecule binds with the mRNA molecule?
- Amino Acid
- tRNA
- Anticodon
- Codon
Hint:
This tRNA's anticodon is complementary to the mRNA's initiation codon
The correct answer is: Anticodon
- Each triplet codon of the DNA contains an anti-codon
- A tRNA anticodon pairs with its complementary codon on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the polypeptide
