Codons for Leucine are CUU, CUC, CUA, CUG, UUA, UUG . Out of these, CUU, CUC, CUA, CUG can be read by 1 t-RNA (as they satisfy conditions for Wobble hypothesis). But UUA and UUG can only be read by another t-RNA as even though they code for same amino acid they are very different form CUU, CUC, CUA, CUG . Thus at least two different t-RNAs are required for reading all codons of Leucine
