Genetic Code vs. Codon: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on December 7, 2023
The genetic code is the set of rules by which information encoded in DNA is translated into proteins, while a codon is a specific sequence of three DNA or RNA nucleotides that corresponds to an amino acid.

Key Differences

The genetic code is a universal set of rules that determine how nucleotide sequences are translated into proteins. However, a codon is a specific combination of three nucleotides within this code.

Each codon specifies an amino acid or a stop signal during protein synthesis. While, the genetic code encompasses all possible codon combinations and their corresponding amino acids.

The genetic code is consistent across most organisms, highlighting its fundamental role in biology. Each codon within this code is essential for accurate protein synthesis.

In the genetic code, multiple codons can encode the same amino acid, a feature known as redundancy. A codon itself is specific to one amino acid or a stop signal.

The genetic code provides the blueprint for building proteins from genes. In this process, each codon in a messenger RNA (mRNA) molecule is read and translated.

Codon

(biochemistry) A sequence of three adjacent nucleotides, which encode for a specific amino acid during protein synthesis or translation.

Codon

A sequence of three nucleotides in a genome or a DNA or messenger RNA molecule, which specifies the incorporation of one amino acid or is a stop signal, during the biosynthesis of proteins. Codons occur within the protein-coding segments of the DNA or RNA genome of living organisms. The amino acid sequence of proteins synthesized on ribosomes is thus determined by the sequence of the nucleotides in the genome.
