genetic mutations

Researchers discovered which genes are required for each stage of cell differentiation into neural stem cells and neurons, i.e. for brain development, and which of them are involved in diseases of the nervous system
One of the diseases resulting from such mutations in the PHOX2B gene is the disease CCHS. This is a rare and life-threatening syndrome in which babies, children and adults stop breathing as soon as they fall asleep. The patients must be connected to ventilators in order not to die in their sleep
The human DNA molecule contains about three billion bases and replicates every day about two trillion times. For the cellular structure to be preserved, the replication process must be incredibly precise, but at the same time, the appearance of mutations shows that the process is not immune to errors. With the help of computer simulations, physicists and chemists from the University of Surrey In England they showed that errors in replication may occur due to quantum tunneling.
