1. Isoleucine  - ATT, ATC  and ATA

2. Leucine -  CTT,CTC,CTA CTG, TTA and TTG.

3. Valine - GTT, GTC, GTA and GTG.

4. Phenylalanine - TTT and  TTC.

5. Cysteine - TGT and  TGC

6. Alanine - GCT, GCC and GCG

7. Glycine - GGT, GCC, GGA and GGG.

8. Proline - CCT, CCC, CCA and CCG.

9. Threonine - ACT, ACC, ACA, and ACG.

10. Serine - TCT, TCC, TCA, TCG, AGT and AGC.
