Create an RNA File

How do I work with RNA files in SnapGene?

SnapGene 5.3 and later have a specific RNA file type (extension .rna).  Earlier versions of SnapGene will import RNA sequences as DNA.

Open the New DNA or RNA Window

Click menu File → New DNA or RNA sequence.

Enter the RNA sequence

Set "Sequence Type" to RNA.

Enter a sequence comprising A, G, C or U (uracil).

Set the "Topology" to "Single-Stranded" or "Double-Stranded" and set whether the new sequence is "Linear" or "Circular".

Set the "File Name", then click OK to create a new RNA sequence.

Click File → Save to save the new sequence to an appropriate location on your computer.
