Optional
_lengthOptional
_sequenceActual 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
_subunitIndex 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
Optional
extensionAdditional content defined by implementations
Optional
fiveThe 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
Optional
idUnique id for inter-element referencing
Optional
lengthThe length of the sequence shall be captured
Optional
linkageThe linkages between sugar residues will also be captured
Optional
modifierExtensions that cannot be ignored even if unrecognized
Optional

Optional
sugar5.3.6.8.1 Sugar ID (Mandatory)
Optional
threeThe nucleotide present at the 3’ 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 last position in the sequence. A separate representation would be redundant
The length of the sequence shall be captured
