Answer Details
In adult mammalian blood, the cells which lack nuclei are the erythrocytes, also known as red blood cells. Erythrocytes are responsible for carrying oxygen from the lungs to the body tissues and carbon dioxide from the tissues to the lungs. The absence of a nucleus in erythrocytes allows more space for the oxygen-carrying molecule hemoglobin, which enables them to transport more oxygen. Without a nucleus, erythrocytes are not able to divide, repair themselves, or synthesize new proteins.
