Copy a DNA/RNA sequence as reverse/complement/reverse complement and paste the result in any other app.
If you highlight text that represents a DNA/RNA sequence (e.g. 'GGTaaat') on a page and right click, the extension provides you with the options to "Copy as reverse", "Copy as complement" and "Copy as reverse complement". Clicking one of those entries will copy the selected text and apply the conversions. You can then paste the converted sequence in any application on your computer.
