What are the standard nucleotides not considered as “Modified Nucleotides” according to MPEP 2412.03(e)?
MPEP 2412.03(e) provides a list of standard nucleotides that are not considered “Modified Nucleotides”. These are: deoxyadenosine 3′-monophosphate deoxyguanosine 3′-monophosphate deoxycytidine 3′-monophosphate deoxythymidine 3′-monophosphate adenosine 3′-monophosphate guanosine 3′-monophosphate cytidine 3′-monophosphate uridine 3′-monophosphate These nucleotides represent the standard DNA (first four) and RNA (last four) building blocks. Any nucleotide that is not one of these standard…

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…

How are nucleotide bases represented in a sequence listing? Nucleotide bases in a sequence listing are represented using specific symbols as outlined in WIPO Standard ST.25 and referenced in MPEP 2423.01. The representation follows these guidelines: Use the one-letter code for nucleotide sequence bases: A, C, G, T for DNA; A, C, G, U for…
