Codons for Leucine are$\mathrm{C}\mathrm{U}\mathrm{U},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{C},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{A},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{G},\mathrm{ }\mathrm{U}\mathrm{U}\mathrm{A},\mathrm{ }\mathrm{U}\mathrm{U}\mathrm{G}$. Out of these,$\mathrm{C}\mathrm{U}\mathrm{U},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{C},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{A},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{G}$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$\mathrm{C}\mathrm{U}\mathrm{U},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{C},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{A},\mathrm{ }\mathrm{C}\mathrm{U}\mathrm{G}$. Thus at least two different t-RNAs are required for reading all codons of Leucine
