pGEM-3Z digested with MspA1I
MspA1I recognises CMGCKG and cuts circular pGEM-3Z (GenBank X65304.3, 2,743 bp) at 6 sites, so a complete digest gives 6 fragments.

Positions are in the numbering of GenBank X65304.3. A cut after base n leaves base n at the end of one fragment and the next base at the start of the next. A fragment that runs past the record's last base continues from its first. A vendor's map, or your own stock, may differ from this record.
The same question is open below in Drybench Plasmid. Change the enzymes, the host's methylation or the vector there; nothing you do here is saved unless you save it.

Opening what was sent…
Not medical advice. For research and education only, and not medical advice: this app designs restriction, Golden Gate and Gibson products from the sequences you supply; a designed product is not evidence that the reaction occurred, and nothing here predicts whether a reaction works, how well, or whether the product is expressed.
Ends
MspA1I: CMGCKG, cut CMG^_CKG, leaving blunt ends.
Methylation
Every one of these sites is cut in unmethylated DNA and in DNA from a dam and dcm methylating host, by the recorded dam and dcm sensitivities. Only dam and dcm are considered; CpG, EcoKI and other modifications are not modelled.

The workspace draws a schematic gel of these fragments, not a prediction of where bands will run. Fragments under 100 bp are listed here but not drawn there, and fragments within 5 percent of each other are drawn as one band.
How this page was made
Computed when the site was built by the Drybench Plasmid engine, version 1.0.0, from /data/plasmid-map/examples/pgem-3z.1.json (GenBank X65304.3, SHA-256 4f560f61d69429fe294d5d5218159d1e5c69a7025ce66fc439c680ef7ffb6b9a) and enzyme table version 1, /data/plasmid-map/enzymes.8829d35c83.json (2026-10-06). Every cut position and fragment length on this page was compared with Biopython 1.88 (REBASE release 404, recorded 2026-11-07); a disagreement stops the build.
