The genetic code is redundant. What is meant by this statement?

This means that one amino acid can be coded by more that one codon.

Explanation:

A triplet code that code for an amino acid during translation is called genetic code. The genetic code is said to be redundant because a single amino acid can be coded by more that one triplet codon.

So there can be synonymous codon for one amino acid. For example, leucine, serine, and arginine have 6 synonymous codons.

The genetic code is unambiguous also because each triplet codon can only code for a particular single amino acid. Genetic code is also universal which means the same code is used in all life forms.
