Answer:

In case of the amino acid Leucine only, there are six different codons (TTA, TTG, CTT, CTC, CTA, CTG) that the tRNA can recognize and translate. Since there is only one codon that needs to be translated, only one tRNA is required.

Explanation:

The anti-codon on the tRNA recognizes the complementary bases on the codon, and because of the third-base wobble feature, there isn't a 1:1 ratio between the number of codons present and the anti-codons required.

Hope that answers the question. Have a great day!
