What symbols are used for termination codons in amino acid sequences?

According to MPEP 2412.05(d), termination codons in amino acid sequences are represented by specific symbols:

• An asterisk (*) is used to represent termination codons in amino acid sequences.
• The MPEP states: “The symbols set forth in Table 3 of Appendix G should be used to represent amino acids. Termination codons should be shown as an asterisk (*).“
• This symbol is universally recognized in sequence listings and helps distinguish the end of a coding sequence.

It’s important to use this standardized symbol to ensure clarity and consistency in patent applications involving amino acid sequences.
