Key Concepts

Universal Genetic Code

This concept refers to the fact that nearly all organisms on Earth use the same set of codons to specify amino acids during protein synthesis. It means that the mechanisms and rules of translating nucleotide sequences into proteins are highly conserved across different species.

Codon

A codon is a sequence of three nucleotides in messenger RNA that corresponds to a specific amino acid or a stop signal during the process of protein synthesis. The structure and function of codons are fundamental in translating genetic information into functional proteins.

Genetic Code Redundancy

Also known as degeneracy, this concept describes how multiple codons can code for the same amino acid. This redundancy provides a buffer against point mutations, as changes in the nucleotide sequence may not necessarily alter the amino acid sequence of a protein.
