Create a New DNA, RNA or Protein Sequence

  • Updated

How do I create a new DNA or RNA sequence?

Create the Sequence

Use one of the following methods to open the the "New DNA or RNA File" window.

  1. Click menu File → New DNA or RNA Sequence.
  2. Click the + button in the tab bar.
  3. Click the New button on the top toolbar.

In the ""New Sequence" window set the sequence type, topology and name of the new sequence:

  1. If required, use the dropdown to set the "Sequence Type" to DNA, RNA or Protein.
  2. Paste or type an appropriate sequence into the Sequence field.
  3. Set Strandedness and Topology.
  4. Enter a name for the new sequence.

To insert new sequence you can:

  • Manually type a DNA, RNA or protein sequence
  • Paste a plain DNA, RNA or protein sequence
  • Paste a formatted DNA, RNA or protein sequence in either FASTA, GenBank, EMBL, DDBJ or GCG format
  • Paste a DNA, RNA or protein sequence region copied from another open SnapGene file (note you can also Extract a Region in a Sequence to a New File)

Features defined in GenBank, EMBL, DDBJ or GCG formatted text will be added to the sequence.

Check the option to "Detect common features" and SnapGene will automatically detect common features and provide a preview. Lower the "threshold for feature detection" to detect features with lower sequence identity.

Click Create to create a new unsaved sequence file. Click File → Save to save the sequence to an appropriate location on your computer.
