Virtual models for interactive e-learning in Medical Biochemistry

The aim is to produce a collection of own and free virtual models and useful links to Web-sites. Models found illustrate the structure, function and purification of deoxyribonucleic acids (DNA). Selected expensive, complex and dangerous experiments were modeled. Short videos and animations were created as illustrations of real processes. These virtual models cover the techniques for isolation of DNA from cells, the polymerase chain reaction and the steps for direct DNA sequencing. The virtual models and links are useful for self-work, traditional lecture-based and problem-based learning. They are appropriate for regular and distance e-learning in Medical Biochemistry.
