When the sequence has been entered → you will be able to view the Circular/Linear Map on the left-hand side of the screen and detailed features of the sequence on the right-hand side of the screen.Īt the bottom of the page → you will be able to change your sequence type (circular or linear), which will be instantly mirrored on your genetic map. When the sequence is entered → DNA cut sites, promoter regions, open reading frames and primer regions will automatically be outlined. Labstep team tip: You can change the view and the nature of the sequence to linear or circular. View → show all, hide all, features, translations, primers, parts, cut sites, ORFs, sequence case, full sequence translation, axis, axis numbers, reverse sequence, DNA colors, feature labels, part labels, cut site labels, external labels, label line, label line intensity In the GIF below, you can find examples of circular (pUC18 plasmid) and linear (ACTN3 exon 1) DNA sequences.įile → rename, save, read-only, import, export, print, propertiesĮdit → create, cut, copy, paste, undo, redo, find, go to, select, change case, complement selection, complement entire sequence, reverse selection, reverse entire sequence, rotate to caret position Please make sure, both of these are the set the same to avoid confusion by viewing a circular sequence on a linear map and vice-versa. Switch to read only → prevents any editingįind → enables you to search through the sequence Open reading frame → shows ORF Translations and shows GTG and CTG as start Codons Hide primers → enables you to show/hide primers Hide features → enables you to show/hide features Hide cut sites → enables you to filter through which cut sites you want to display Redo → reapplies a change that had previously been deleted Import → imports a sequence to the Sequence editor Tools → add additional enzymes, simulate digestion, remove duplicatesĮxport → downloads a sequence to your device #Add pieces in to plasmid maps snapgene viewer full# Visibility → enables you to select what you want to seeĪdd a plasmid editor widget and you can start to load a sequence and see the features in real time. #Add pieces in to plasmid maps snapgene viewer full#Īll the features will be loaded automatically and the sequence can be changed on the right side of the panel.Īccessing the “edit” tab allows you to create new elements for your sequence.The application does not feature the functionality included in tools of the same feather, but it offers support for the most frequently used operations as far as DNA sequence analysis is concerned. Primers for PCR, sequencing, or mutagenesis can be designed and annotated, too. It sports automatic annotation of common features but it also offers the opportunity to do it manually in the case of coding sequences as well as more particular features. Features at a glanceĪmong the list of features available in SnapGene Viewer there is the possibility to create a DNA sequence file from punching in the sequence and export it to a GenBank format. There are multiple views available that allow toggling the display of enzymes on or off as well as showing the sequences, features or primers. However, a single look at the interface shows that the developers did their best to come up with a layout that is intuitive and comprehensive at the same time.Īs soon as a DNA file is loaded, there is a clear view of the map. User friendly interfaceĭue to the domain it has been built for, SnapGene is not accessible to all users. Getting the application on the system is done through an uneventful installation process that includes the option to associate specific file extensions (sequences, sequence traces and archives) with SnapGene Viewer. The application works with files as large as 1GB. SnapGene Viewer has been designed as a helpful tool for biologists to handle and exchange annotated DNA sequences easier and with less effort. Luckily, some developers provide the necessary digital instruments for analyzing this type of data in an easier way. Working with DNA sequences can be a difficult task, even for those who are familiar with the matter.
