The DNA base sequence GGG
codes for the amino acid proline. Could this
same base sequence code for a different
amino acid? Why or why not?

Answer :

No. Each three letter base sequence, such as GGG is called a “codon”. Each codon makes only one amino acid

No, the GGG nucleotide sequence ONLY codes for the amino acid proline because the genetic code is UNAMBIGUOUS.

  • The genetic code is a set of rules by which genetic information passes from DNA to proteins, i.e., from different triplets of nucleotides to different amino acids.

  • The genetic code is said to be unambiguous because each triplet of nucleotides or 'codon' specifies only a single amino acid.

  • The genetic code is also redundant because different codons can encode the same amino acid.

In conclusion, the GGG nucleotide sequence ONLY codes for the amino acid proline because the genetic code is UNAMBIGUOUS.
