You can perform various operations on the DNA sequence and you can use any DNA sequence no matter how long it is. Franklin allows you to add label to selection, add comments to the selection, select and mark exons, use different colors for labels, search a particular sequence in all the data, etc. You can easily manage the DNA sequence data with the help of this tool and make necessary decisions. However, it doesn’t allow you to export the annotated data. But if you want the data with annotation so badly, then you can try saving the webpage as PDF.
