WebDSV is an online DNA sequence editor and map drawing program. It provides basic analysis of DNA sequences (restriction sites, GC content).

A user can mark sequence features and visualize them along the sequence and in feature map

WebDSV can be used to perform plasmid cloning in silico, design PCR primers, or to plan a gene synthesis

Useful for molecular cloning and synthetic biology

RESTRICTION ENDONUCLEASES

To display the cutting pattern and positions, doubleclick the enzyme name. To apply changes made in the selection, press 'Enter' key or click the 'Apply' button.

QUICK HINTS

  • Basic sequence handling:
    • Paste a DNA sequence in the editor field, open a sequence file, or download a sequence from GenBank.
    • Edit the sequence in the editor field as required, click 'Aplly & Process' after each step.
    • To mark a feature, first select the feature sequence in the editor field then click 'Add Feature'. Edit the feature type and visualization settings in the feature panel.
    • To save a sequence with marked features, use the 'Save GenBank' button.
  • Tips for efficient work
    • The visualization field cannot be used for editing. However, you can easily select a nucleotide position of interest in the editor field by doubleclicking the corresponding nucleotide in the visualization field. Use Ctrl+doubleclick to select spans of nucleotides. Similarly, doubleclicking an amino acid symbol, restriction site or feature label will select the corresponding sequence in the editor field.
    • To perform in silico molecular cloning, doubleclick the first restriction enzyme name in the visualization field, press Ctrl key and doubleclick the second restriction enzyme name. The corresponding DNA fragment will get selected in the editor field. Now you can use Ctrl+C and Ctrl+V for copying the fragment's sequence and pasting it into a target vector sequence already open in another WebDSV browser tab or window.
