About this calculator

The amino acid codon table is an essential tool in molecular biology. It relates the 64 possible codons to the 20 amino acids that make up proteins, as well as start and stop signals. Each codon, a sequence of three nucleotides, encodes a specific amino acid or instruction for protein synthesis.

The table works based on the genetic code, where each codon is translated into an amino acid or a stop (STOP) or start (START) signal. The code is nearly universal, allowing different organisms to use the same table for protein synthesis. This reflects the evolutionary conservation of the translation machinery.

It is crucial to use this table when working with DNA or RNA sequences to predict the amino acid sequence of a protein. This is especially important in bioinformatics, genetic engineering, and gene expression studies. However, care should be taken with synonymous codons that may have different frequencies in different organisms.

When using this calculator, it is essential to remember that the table does not account for factors such as alternative splicing, RNA editing, or specific sequence contexts that may influence actual translation. Therefore, results should be interpreted with care and considered in conjunction with other biological information.

Frequently asked questions

What is a codon?

A codon is a sequence of three nucleotides that encodes an amino acid or a start or stop signal for translation.

What are the types of codons?

There are 64 possible codons, which encode 20 amino acids, start (START) and stop (STOP) signals for translation.

How to use this table?

Simply enter the desired codon to see which amino acid or type of signal it encodes.

What precautions should I take?

Remember that the table does not consider factors such as alternative splicing or RNA editing, and that synonymous codons may have different frequencies in different organisms.

What is it used for?

It is used to predict the amino acid sequence of a protein from a DNA or RNA sequence.
