Learn what the three stop codons are. Identify the functions of the start and stop codons, study codon diagrams, and discover mutations of stop codons in DNA.

A codon is a three-letter genetic sequence found in both DNA and RNA. It codes for a specific amino acid, or start and stop signals, for the protein synthesis process.

A codon is a sequence of three nucleotides, which codes for one amino acid. Living things read codons and use the genetic code to create proteins.

A nonsense mutation results in the insertion of a premature stop codon into the DNA sequence. This results in translation terminating early and a truncated protein.

A nonsense mutation is a mutation that introduces a stop codon into the genetic code and prevents the protein from being made completely. How do you identify a silent mutation?

There are three types of a codon: start codon - which initiates the translation into proteins; normal codon - which codes for different amino acids involved in the elongation process; and stop ...

A nonsense mutation occurs when a change in the DNA sequence leads to a stop codon, resulting in the termination of translation and truncation of the protein.
