Racket (formerly PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, tools for creating stand-alone executables, the Racket Web server, extensive libraries, documentation for both beginners and experts, and more. It supports the creation of new programming languages through a rich, expressive syntax system. Example languages include Typed Racket, ACL2, FrTime, and Lazy Racket.
StarORF is a tool that facilitates the identification of the protein(s) encoded in DNA sequences and allows for transforming input sequence in its reverse complements. It allows students to define the minimal ORF length detected and highlighted by the software. Students can see putative ORF protein sequence (longer than specified ORF length), visualize start and stop codons in the sequence, and navigate imported sequences. The StarORF site contains a software user manual, video tutorial, and exercises applicable to high school and college classrooms.
