Red blood cells are ennucleated. They do not contain genetic information. Their cellular machinery is pared down to perform the specific tasks they are handed (gas exchange).

How can a virus use the cell machinery of the blood cell?
it is because virus does not have a cell machinery to divide itself. when it comes to affect our body's tissue, it uses the blood cell's machinery to divide and infect other blood cell.
Can a mature red blood cell divide?
No, it cannot divide since mature red blood cells have no nucleus. there are no chromosomes to replicate.
Can red blood cells divide if blood is lost?
No, red blood cells cannot perform cell division as they do not have a nucleus. They are instead produced in the bone marrow by the division of stem cells.
A human red blood cell has no chromosomes How does this affect the red blood cell's ability to divide?
They do not divide. The process by which red blood cells are produced is called erythropoiesis. Red blood cells are continuously being produced in the red bone marrow of large bones, at a rate of about 2 million per second.But many people might wonder "how we could produce so many red cells each second without chromosomes which hold a cell's directions for HOW to divide and multiply!" The answer lies in realizing that, unlike many tissue types (skin, muscle, live, etc) that divide and produce two mature tissue cells, red blood cells go through several stages of developmentActually, a human red blood cell DOES have chromosomes, and they DO divide. But, as noted above, this situation exists only in the early life stagesof a red blood cell ( that is, the early stages of erythropoiesis) and these stages take place only in the bone marrow. All the dividing occurs during a red blood cells "infancy", so to speak. (You wouldn't recognize them though, as each is a big cell with a big nucleus - nothing like the common, tiny, nucleus-free "adult" red blood cells. By the time it's an adult, a red blood cell will have lost it's nucleus.) The mature adult red blood cellsdrawn from someone's vein are only the final stage in a red blood cell's life, but for most people these are the only red blood cells they have ever seen.So, although it is true for the red blood cells you've probably seen, try making a small change in your mindset from "theydo not divide", to ""Adult red blood cells do not divide". That solves the mystery. (Besides, they don't have to! Did that; been there. Now they get to coast - as tiny, flexible oxygen delivery guys.) -John Bohn, MD
What are the disadvantages for a cell that does not divide?
If a cell does not divide, and it is destroyed, it cannot grow back and you will have a cell shortage. Like the brain cell
Kind of a cell that does not have a nucleus?
Kind of cell that does not have a nucleus?
What does a white blood cell have that a red blood cell doesn't?
The white blood cell has nucleus that red blood cell does not
What is that a cell contiously divide?
A cancerous cell.
How does the cell doctrine contradict with a mature red blood cell?
Red blood cells are considered cells, but they lack all organelles. Red blood cells cannot divide or replicate like other cells of the body. The blood's red color is due to the spectral properties of the hemic iron ion the hemoglobin. Each human red blood cell is packed with approximately 270 million hemoglobin biomolecules.
Which cells don't divide?
Brain cell do not divide in later life. Cardiac muscle divides itself less than 1% each year in humans.
What is a type of cell that does divide actively?
A meristematic cell
Why must the cell divide?
Cells Must divide: for health (white blood cells will increase in #'s in response to a virus attack) for regeneration (replacement of aging cells) for growth (accumulation of cells) for repair for differentiation or specialization of cell type reproduction (single-celled) organisms efficiency of exchange of materials across cell membrane
