Optional_Optional_Actual nucleotide sequence notation from 5' to 3' end using standard single letter codes. In addition to the base sequence, sugar and type of phosphate or non-phosphate linkage should also be captured
Optional_Index of linear sequences of nucleic acids in order of decreasing length. Sequences of the same length will be ordered by molecular weight. Subunits that have identical sequences will be repeated and have sequential subscripts
OptionalextensionAdditional content defined by implementations
OptionalfiveThe nucleotide present at the 5’ terminal shall be specified based on a controlled vocabulary. Since the sequence is represented from the 5' to the 3' end, the 5’ prime nucleotide is the letter at the first position in the sequence. A separate representation would be redundant
OptionalidUnique id for inter-element referencing
OptionallengthThe length of the sequence shall be captured
OptionallinkageThe linkages between sugar residues will also be captured
OptionalmodifierExtensions that cannot be ignored even if unrecognized
OptionalsequenceActual nucleotide sequence notation from 5' to 3' end using standard single letter codes. In addition to the base sequence, sugar and type of phosphate or non-phosphate linkage should also be captured
