1) The document describes a computational tool called RASA-GD that was developed to extract and analyze genetic data from GenBank files in a more readable graphical format.
2) RASA-GD accepts GenBank files as input, extracts information on coding regions, exons, introns and other elements, and calculates statistical values and generates graphs of the length variations.
3) As a demonstration, the tool was used to visualize and analyze variations in the foxp2 gene, which is responsible for speech, across different species. The data generated insights into the evolutionary history of this gene.
