One step is the minimum required to separate nuclei from ribosomes in a cell lysate by centrifugation.
During experiments dealing with molecular biology, centrifugation is essential to promote the separation of biological molecules.
In these experiments, centrifugation is done in a machine, where the scientist can choose the speed at which the centrifugation will be performed. Depending on the speed chosen and the materials centrifuged, only one centrifuge step will be necessary.
An example of this can be seen in centrifugation to separate nuclei from ribosomes in a cellular lysate, where only one step is needed.
