about 100-120 days
This would be normal. All body cells have the same DNA, including blood cells, at least at some point during their life cycles. Mature red blood cells do not contain DNA because they do not have cell nuclei. But when red blood cells are first formed, they do have a nucleus with DNA identical to the rest of the body cells.
Brain cell do not divide in later life. Cardiac muscle divides itself less than 1% each year in humans.
when mature egg cells leave the ovary
Red blood cells don't have nuliets however white blood cells do. Red blood cells can have an average life-span of 120 days while white blood cells do not have an average life span. Also, white blood cells are larger than red blood cells.
well you dont want your blood cells to big or to small the red blood cells are what keeps your blood flowing the correct way so yes red blood cells are life threatening.

Mature+ Blood and gore 17 or older.
One thing that is significant about a red blood cell being anucleate is that it has a limited life span. It also does not reproduce.
Red blood cells carry oxygen through your body.
Hemolytic anemias are conditions in which the blood is low in oxygen because the red blood cells are breaking down at a faster rate than their normal life expectancy of 120 days.
They do. Mammals are the only vertebrates without a nucleus in their erythrocytes.
Red blood cells have no nucleus while a typical animal cell does. This is essential for its function because it needs to hold the hemoglobin molecules that carry oxygen and carbon dioxide. The drawback to this is that it does not have the ability to reproduce. So the life span of most red blood cells is typically 120 days.
