Red blood cells are missing the nucleus , a cell part found in virtually all other cells.

Quick Scoop

Most body cells have a nucleus, which stores DNA and controls the cell’s activities.

Mature red blood cells (erythrocytes), however, lose their nucleus as they develop.

This has two big consequences:

  • It creates more space inside the cell for hemoglobin, the protein that carries oxygen.
  • It means red blood cells cannot divide or repair themselves and therefore have a limited lifespan.

So, for the exam-style question “which cell part, found in virtually all cells, are red blood cells missing?” the answer is: the nucleus.
