A nucleus
Red blood cells lack a nucleus.
Most cells you see will be red blood cells (erythrocytes) and they lack a nucleus in their structure.
Red blood cells are the only cells in the body that lack a nucleus.
Red Blood Cells
It is actually the other way around - mature red blood cells lack a nucleus.
If red blood cells lack Rh antigens, the blood is called Rh-negative.
Most blood cells are red, because the red cells are the most numerous blood cells.
Red blood cells or erythrocytes are small biconcave blood cells that lack a nucleus when they are mature and carry oxygen throughout the body. They lack the nucleus and most organelles in order to maximize room for hemoglobin. The cells are active for about 100â??120 days. New cells are made in the bone marrow.
Red blood cells are considered cells, but they lack all organelles. Red blood cells cannot divide or replicate like other cells of the body.
Yes, but not very much. Red blood cells lack most of the typical organelles of a cell, including a nucleus and mitochondria.
Red blood cells, also known as erythrocytes, lack a nucleus.
This is a biology question, but the answer is Prokaryotic. ------------------------------------------------------------------------------------ Red blood cells also lack a nucleus.
