Give an example of an amino acid being coded for more than one codon

Many of the amino acids are coded for by more than one codon. Examples are:

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. 

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
