Give examples of non-nuclear cells. Explain the reason for their non-nuclear weapons. What is the difference between the life of nuclear-free cells and cells with a nucleus?

Prokaryotes – cells of microorganisms, instead of a nucleus, contain chromatin in the cell, which contains hereditary information.
In eukaryotes: mammalian erythrocytes. In place of the nucleus, they contain hemoglobin and, therefore, the binding of O2 and CO2 increases, the oxygen capacity of the blood – gas exchange in the lungs and tissues is more efficient.
