is one codon specified only for one amino acids but one amino acids can represented by different codon
1 answer
Yes, one codon is specified for one amino acid. However, it is possible for one amino acid to be represented by different codons. This is due to the redundancy of the genetic code. For example, the amino acid alanine can be encoded by the codons GCU, GCC, GCA, and GCG. This redundancy provides some protection against mutations or errors in the DNA sequence, as a change in the third position of the codon may not always result in a different amino acid being incorporated into a protein.
