It has been shown, for instance, that the same fRNA can recognise more than one codon differing only at the third position. This pairing is not very stable and is allowed due to wobbling in base pairing at this third position. This kind of wobbling allows economy of the number of fRNA molecules, since several codons meant for the same amino acid are recognised by the same fRNA. For instance, anticodon CGC can recognise codons GCU, GCC and GCA.

Assertion: Same RNA can recognize more than one codon differing only at the third position.
Reason: The specificity of a codon is particularly determined by the first two bases.
Explanation:
Conclusion:
The assertion is correct as same RNA can recognize more than one codon differing only at the third position. The reason is also correct as the specificity of a codon is mainly determined by the first two bases. However, the reason does not fully explain why the same RNA can recognize multiple codons. The flexibility of the third position and the phenomenon of wobble base pairing play a significant role in this recognition. Therefore, the correct answer is option A - Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
Reason: The specificity of a codon is particularly determined by the first two bases.
Explanation:
- RNA and Codons: RNA is a molecule involved in the process of protein synthesis. It consists of a sequence of nucleotides, and each group of three nucleotides is called a codon.
- Unique Codons: There are a total of 64 different codons in the genetic code, including 61 codons that encode for amino acids and 3 codons that act as stop signals.
- Redundancy in the Genetic Code: The genetic code is considered to be redundant because multiple codons can specify the same amino acid. For example, the amino acid leucine is encoded by 6 different codons: UUA, UUG, CUU, CUC, CUA, and CUG.
- Third Position Variability: The third position of the codon is often referred to as the "wobble position" because it exhibits more flexibility in base pairing compared to the first two positions. This flexibility allows for the recognition of multiple codons by the same RNA molecule.
- Base Pairing Rules: The specificity of a codon is primarily determined by the first two bases. The third base, although it can vary, does not significantly alter the specificity of the codon. This is because of the phenomenon of "wobble base pairing," where the third base can form non-standard base pairs with the corresponding base in the anticodon of the tRNA during translation.
Conclusion:
The assertion is correct as same RNA can recognize more than one codon differing only at the third position. The reason is also correct as the specificity of a codon is mainly determined by the first two bases. However, the reason does not fully explain why the same RNA can recognize multiple codons. The flexibility of the third position and the phenomenon of wobble base pairing play a significant role in this recognition. Therefore, the correct answer is option A - Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
