Here, we have a collection of videos and experiments that are suitable for Biology.
Na+ - K+ Pump
This video describes the actions of the Na+ - K+ pump in keeping an ion gradient across the cell membrane.
This video shows the growth of long extensions called neurites from neuronal precursor cells.
In the embryonic brain of the frog Xenopus, neurons extend axons from the eye to connect to appropriate target cells in the midbrain. This video shows the growth of these neuronal connections.
Nuclear Envelope Assembly
This video shows the assembly of a nuclear envelope over DNA.
