How does WIPO Standard ST.26 define “unknown” or “other” nucleotides and amino acids?
MPEP 2412.03(a) refers to WIPO Standard ST.26, which defines “unknown” or “other” nucleotides and amino acids using specific symbols: For nucleotides, the symbol “n” represents “unknown” or “other” For amino acids, the symbol “X” represents “unknown” or “other” The MPEP provides tables for both nucleotide and amino acid symbols, stating: n a or c or…

What symbols are used for termination codons in nucleotide sequences? According to MPEP 2412.05, termination codons in nucleotide sequences are represented by specific symbols: “The symbols “TAA,” “TGA,” or “TAG” should be used to represent termination codons.” This means that when including a termination codon in a nucleotide sequence listing, you should use one of…

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…

According to MPEP 2422.01, nucleotide and amino acid sequences in patent applications are represented as follows: Nucleotide sequences: Represented by symbols set forth in 37 CFR 1.822(b) and Appendices A and B to 37 CFR part 1, Subpart G. Amino acid sequences: Limited to those in 37 CFR 1.822(b) and Appendices C and D to…

According to WIPO Standard ST.26, paragraph 13, all nucleotides in a sequence must be represented using the symbols in Table 1: List of Nucleotides Symbols. Only lowercase letters must be used. The most important symbols are: a – for adenine c – for cytosine g – for guanine t – for thymine in DNA or…

According to WIPO Standard ST.26, amino acids in a sequence must be represented using the one-letter codes specified in Table 3: List of Amino Acids Symbols. Key points include: Only uppercase letters must be used. Each symbol represents only one residue. Use the most restrictive symbol for ambiguities (e.g., “B” for Asp or Asn, not…
