Question

What is the location of anticodon?

Answer 1

The anticodon is a sequence of three nucleotides found on a transfer RNA (tRNA) molecule. It is essential for ensuring the accuracy of protein synthesis by helping tRNA recognize and bind to the complementary codon on messenger RNA (mRNA).

The anticodon is located at one end of the tRNA molecule, opposite the site where the amino acid is attached. The anticodon region is critical in protein synthesis because it is responsible for recognizing and binding to the complementary codon present on the mRNA during the process of translation. This ensures that the correct amino acid is added to the growing polypeptide chain.

Anticodon Location: The anticodon is situated on a specific loop of the tRNA molecule known as the anticodon loop or anticodon arm. This loop contains the three nucleotides that are complementary to the codon on the mRNA strand.

The process works as follows:

• The anticodon of tRNA binds to the complementary mRNA codon via complementary base pairing (A-U, G-C).
• This interaction ensures that the correct amino acid, attached to the tRNA, is added to the growing polypeptide chain during translation.

Key Points:

• The anticodon consists of three nucleotides that are complementary to the mRNA codon.
• The anticodon is located on the anticodon loop of the tRNA molecule.
• Accurate pairing between the anticodon and codon ensures the correct translation of the genetic code into protein.

Summary: The anticodon on tRNA plays a crucial role in protein synthesis by matching with the mRNA codon. This interaction ensures that the correct amino acid is added to the polypeptide chain, maintaining the accuracy of genetic translation.
