The Cell Cycle is the process by which cells grow and then divide to form new cells. This cell division happens throughout our bodies; from the production of new blood cells in our bone marrow to the generation of new layers of skin cells.

In this video we talked to Professor Peter Burgers about his work on Cell Cycle checkpoints. This is when the Cell Cycle stops so the DNA can be repaired, which is necessary because DNA bases can be damaged by chemicals or radiation between cell replications.

Professor Burgers visited from Washington University to collaborate with Imperial’s own Professor Xiaodong Zhang on checkpoint activator proteins like 9-1-1 that stop the Cell Cycle at the designated checkpoints in order for cell DNA to be repaired.
