When our cells copy their DNA to grow and replicate, it’s vital the process runs smoothly. To get this right, cells use a complex “machine”, made from many hundreds of components. This machine is built afresh, moment by moment as it’s needed during the copying process. This assembly–de-assembly is vital to accurate and efficient copying.
