The cell is a structure that is criss-crossed by flows: flows of energy, matter, and information. The major carrier of the flows of information is the genetic material that holds genetic information. This consists of a molecule with a relatively simple structure: DNA. In effect, there are 4 bases combined in this molecule.How can a molecule with a seemingly simple structure contain all the information on an individual’s characteristics? How is this information expressed? How is this information preserved during cell division whether it is mitosis or meiosis? Animated sequences plunge us into and guide us through this mystery. Grab on to one of the passing genetic flows and come surf!http://www.evolution-of-life.com/en/explore/simulation/fiche/the-flow-of-genetic-information.html
