Mitosis (DVD download)

Accurate transmission of genetic information.
Cellular multiplication is accompanied by the accurate transmission of the genetic heritage, as shown by clones. The mechanism of this transmission is revealed in accelerated microcinematography of plant mitosis.
Fixed views of animal mitosis demonstrate the generality of the process.
An animation reconstructs all the observed phenomena.
Explanation at the molecular level: starting from a karyotype, a 'shattered' chromosome with the DNA molecule unwound is observed.
After an animation, direct observation shows the duplication on the chromatids of a DNA sequence marked by immunofluorescence.
