I'm having trouble determining what exactly is meant by the term "Origin" in this case. It is just before a 70 bp sequence that the page claims is a plasmid, but does not specify it to be what I assume is incomplete, seeing as I don't think there is such a thing as a 70 bp plasmid (correct me if I'm wrong). So do they mean the origin of replication to the plasmid?

Here is the page in question: https://www.ncbi.nlm.nih.gov/nuccore/M30888.1?report=genbank

The ORIGIN may be left blank, may appear as "Unreported," or may give a local pointer to the sequence start, usually involving an experimentally determined restriction cleavage site or the genetic locus (if available). This information is present only in older records.

The sequence data begin on the line immediately below ORIGIN.


Given that it's left blank in your file, it doesn't signify anything other than the end of the annotation and beginning of the raw sequence.
