OnScreen DNA Lite free
OnScreen Science today announced that OnScreen DNA Lite, the entry-level edition of its software for learning the structure and function of DNA, is available for free via download. OnScreen DNA Lite uses a 3D virtual model in a tutorial framework to teach the structural details of DNA, including its double helix geometry and chemical components and bonds. The software also includes animated simulations of biotech lab phenomena in which the two strands of DNA are seen to separate and then reattach. OnScreen DNA Lite requires Mac OS X 10.3.9 or later.
OnScreen DNA's simulations show details that are impossible to see with the two-dimensional "ladder" animations commonly encountered on the internet, according to the company. While aimed primarily at biology teachers, the software is also utilized by others as a self-teaching aid.
OnScreen DNA adds 3D simulations of the critical DNA processes of replication and gene transcription. The Pro edition enables users to take control of those simulations to construct DNA and RNA molecules through the proper choice of enzymes and molecular building blocks.
