In Silico Assembly vs Restriction Simulation: Two Map Jobs
In silico assembly versus restriction-digest simulation are two map jobs, not two names for the same preview. Assembly builds a virtual construct with junctions. Restriction simulation cuts a sequence you already believe and predicts fragment sizes. A pretty output from one button is not proof of the other. Choosing the assembly chemistry is a different page. So is verifying a clone by digest.
Building a Virtual Construct Is Not Predicting a Gel
The search is in silico assembly vs restriction simulation. The first job joins fragments into a new molecule: restriction-ligation, Gibson, or another method the software actually implements. The second job asks what bands a named enzyme set should produce from a sequence. The ApE paper describes both inside one program: in silico simulation of cloning methods to generate a working plan, and gel simulation to confirm an analytic result. That is the split. It is not a reason to treat every canvas as the same evidence.
Diagnostic versus cloning digest jobs change which enzymes you pick. This page changes which software job you think you ran.
Two Map Jobs, Two Outputs
| Dimension | In silico assembly | Restriction-digest simulation |
|---|---|---|
| Input | Fragments, ends or overlaps, and a join rule | One sequence and a named enzyme set |
| Output | A new map with junctions and, if claimed, a reading frame | Predicted fragment sizes and, often, a virtual gel |
| What it can support | That the planned join is geometrically possible in the software's model | That a later wet digest should be readable if the sequence is true |
| What it cannot support | A wet clone, or a gel you have not run | That the junctions were built correctly |
| Typical next step | Order oligos or fragments; then simulate the diagnostic digest | Run the wet digest, or pick enzymes on the diagnostic page |
A digest planner is honest about its job: fragment sizes and an agarose-like pattern. It is not an assembly builder. Software-selection pages often list both features in one sentence. Listing them together is how labs collapse the jobs. Workflow-software criteria still own tool choice. This page owns the two previews those tools expose.
When You Need Both Jobs
Build the virtual construct first. Confirm junctions and frame on that new map. Then simulate the diagnostic digest you will actually load. Skipping assembly simulation and trusting a gel preview of an old backbone is how an insert is drawn and never joined. Skipping the digest simulation and trusting the assembled cartoon is how a clone is “verified” before a band exists. A worked pattern is one Gibson join that produces a new circle, followed by a two-enzyme diagnostic prediction on that new circle — two jobs, two outputs. You can skip assembly simulation only when the molecule already exists as a confirmed file and the only remaining question is which diagnostic cut will be readable. You can skip digest simulation only when the next wet step is not a gel, for example a sequencing read of the junction. Neither skip is a reason to treat the remaining preview as the missing job. The wet digest page owns the bench confirmation. Do not pretend the virtual gel is that confirmation.
Name the Job Before You Trust the Preview
Say which job you are running before you believe the picture. After the job is named, ZettaGene can hold the map. Official product pages list simulation of restriction-enzyme digestion, Gibson assembly, and homologous alignment. Golden Gate is not a Zetta feature on those pages. If the lab's chemistry is Golden Gate, the method page can discuss the chemistry. The product still does not simulate it. A workspace that only paints a circle has done neither job.
Frequently Asked Questions
Does a restriction-digest simulation prove the virtual assembly is correct?
No. Predicted bands test a cut on a sequence you already believe. They do not rebuild the junctions.
Does ZettaGene simulate Golden Gate assembly?
No. Official product pages list restriction-enzyme digestion, Gibson assembly, and homologous alignment. Golden Gate is not a listed Zetta simulation.
