All our cells contain the exact same DNA sequence but one central question remains unanswered - how does a cell know which combination of the 20,000 genes it should activate to produce its specific toolkit? A study co-led by Dr Ben Davies has been published on the Nature Cell Biology website.
Our bodies are composed of trillions of cells, each with its own job. To be able to perform these specific jobs, every cell needs a different set of tools, which are formed by the collection of proteins that a cell produces.
