REDUCE YOUR SIZE A BILLION TIMES AND ENTER THE CELL NUCLEUS!
The first part of the Centre provides an insight into the cell nucleus. This central cell organelle houses most of the genetic information. Unique 3D models show the DNA double helix structure, carrier of genetic information. Its real size in cross-section corresponds to nanometres. To see it in this proportion you would have to get a billion times smaller.
