6.2 Sequences that need to be itemised in the sequence listing
6.2.4 The "mol_type" qualifier
The "source" feature key is mandatory for every sequence, in addition to the qualifiers "organism" and "mol_type" (paragraph 75 of WIPO Standard ST.26).
The value of the "mol_type" qualifier has to be selected from a list of predetermined terms as defined in Annex I of WIPO Standard ST.26 (section 6, qualifier mol_type 6.39; section 8, qualifier mol_type 8.1) and shown in the following table:
DNA |
RNA |
AA |
|---|---|---|
genomic DNA other DNA unassigned DNA |
genomic RNA mRNA tRNA rRNA transcribed RNA viral cRNA other RNA unassigned RNA |
protein |
The value "genomic DNA" does not imply that the molecule is nuclear (e.g. organelle and plasmid DNA must be described using "genomic DNA").
Ribosomal RNA genes must be described using "genomic DNA".
The value "rRNA" must only be used if the ribosomal RNA molecule itself has been sequenced.
The values "other RNA" and "other DNA" must be applied to synthetic molecules, i.e. molecules that have been artificially created.
The values "unassigned DNA" and "unassigned RNA", on the other hand, must be used for molecules that have been isolated from an organism but their nature is not known or not disclosed and they cannot be assigned to any more precise qualifier value (e.g. it is not known whether the sequence is a tRNA or an mRNA or another type of natural RNA).
