Our bodies are made up of millions upon millions of living cells each housing a mass of molecules. This biological machinery is responsible for turning the genetic information encoded within our DNA into flesh, blood, bone and brain – microscopic, hidden processes made visible by this detailed animation. The video captures the bustling business of life from the seething surface of a stem cell to the careful copying and coiling of DNA within a cell as it divides. It also reveals how a gene is 'read' to produce haemoglobin, a protein in red blood cells that transports oxygen around the body, showing how a tiny change in this protein can lead to sickle cell anaemia.
BPoD stands for Biomedical Picture of the Day. Managed by the MRC London Institute of Medical Sciences the website aims to engage everyone, young and old, in the wonders of biomedicine. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
