FAQ

What are the most used codons in Sus scrofa?

Use the "Most Used Codons" section to see which codons appear most often in Sus scrofa. The ranking is based on frequency per 1,000 codons.

Which codons have the highest fraction in Sus scrofa?

Use the "Highest Fraction Codons" section to compare synonymous codons for the same amino acid. Single-codon amino acids and stop codons are excluded so the ranking reflects codon preference rather than trivial 1.00 values.

What is the difference between codon frequency and codon fraction in Sus scrofa?

Frequency measures how often a codon appears per 1,000 codons in the dataset. Fraction measures how strongly that codon is preferred relative to alternative codons encoding the same amino acid.

How should I use this Sus scrofa codon usage table for optimization?

Start with the preferred-codon summaries to identify likely defaults, then review the full table below before making codon optimization or expression design decisions.
