OnScreen Science has announced the release of
OnScreen DNA, a 3D visualization tool aimed at high school and college biology teachers and others with an interest in DNA. It costs $199.99.
OnScreen DNA works as a self-contained guided tutorial on DNA’s double helix structure, its chemical components and its biological function, according to the developer. It can also be used as a supplement to other activities. Teachers can project DNA processes, pause and resume them on command.
A free preview of the software — A Taste of OnScreen DNA — is available for download. It includes the first few steps of the gene transcription study activity.
OnScreen DNA is a Universal Binary that works natively on PowerPC and Intel-based Macs. It requires Mac OS X v10.3.9 or higher and a G4 or faster is recommended.
