Millions of human cells are constantly dividing to repair tissue damage and ensure continuity. This is one of the most complex cellular processes, and in order for it to be successful, cells must produce a copy of their genetic material (DNA). Researchers from the Spanish National Cancer Research Centre (CNIO) have discovered the critical role of the POLD3 protein in this DNA replication process; without POLD3, cells do not divide, and even the embryonic development process may be curtailed.
