They are anucleate cells.
Note that only mammals have anucleate red blood cells.

Is an animal cell a prokaryote or a eukaryote?
A Animal Cell is both a Eukaryotic and Prokaryotic Cell. The Blood cells have no nucleus so they are considered Prokaryotic. That is also why they cannot divide and they do not live very long. The other cells are all Eukaryotic.Added:The above is totally wrong. Red blood cells may have no nucleus, as they mature to not have one, but they are still eukaryotic cells and all animal cells are eukaryotic.
Is DNA found in the nulcei of all cells?
Not all cells have a nucleus. Also nuclei is plural many cells only have one nucleus. Generally cells that have a nucleus have DNA in it. It is suspected that originally the nucleus of cells had RNA instead of DNA and it is suspected that some cells still have RNA in their nucleus. A number of viruses use RNA instead of DNA.
Are kidney cells prokaryotic?
No, kidney cells are eukaryotic.All cells in the human body are eukaryotic except one. Red blood cells are, strictly speaking, prokaryotic because they do not have a nucleus but this is a structural adaptation that allows the cells to carry as much oxygen as possible so they are still listed as eukaryotic.
Does mature mammalian RBC have RNA?
No. As part of the RBC maturation process in mammals, the red blood cells loses its nucleus and is no longer able to synthesize RNA. Immature RBC's, called reticulocytes, do still have small amounts of RNA. However, it is atypical to see more then 1% in a healthy blood smear.
Are red and white and light purple a blood cell?
Mammals only have red blood cells, white blood cells and platelets. Platelets may appear purple under the microscope because of the stains used - but they are not referred to as 'purple blood cells'. Some white blood cells (eg. neutrophils and eosinophils) may also appear pink and/or light purple when stained with conventional stains (eg. H&E stain) - the nucleus is usually the most purple area of these cells. However, they are still white blood cells (despite looking pink/purple).

What is blood without red or white blood cells?
It is still blood, just without platelets. It still contains the red blood cells and plasma, which are valuable for use even without the clotting factors. Plasma without clotting factors is serum.

Do prokaryotic cells contains a nucleus?
No they don't. Eukaryotic cells are the ones that contain a nucleus. However, just because prokaryote cells don't contain a nucleus, they still contain DNA. It just floats freely in the cytoplasm.

What vital substance do bacteria cells still have that's found inside the nucleus of plant and animal cells?
DNA is vital to all life and found in the nucleus of plant and animal cells and the cytoplasm of bacteria.
Do Dinosaur fossils have red blood cells?
Yes. There were dinosaur fossils that have been discovered with red blood cells in it. The blood cells were still fresh
Is red blood cell prokaryote or eukaryote?
Red blood cells, despite their lack of a nucleus, is considered to be a eukaryote. This is mainly because the stem cell it originated from had a nucleus, but it disappeared in order to make room to carry oxygen and carbon dioxide. Also, a red blood cell is still part of the kingdom animalia, not monera which is what prokaryotes belong to.
Is erythrocyte a prokaryotic or eukaryotic cell?
No, white blood cells are not eukaryotes.Eukaryotes are organisms that have eukaryotic cells. People are eukaryotes, with many millions of eukaryotic cells.White blood cells are eukaryotic cells in eukaryotes.
3 kinds of blood cells?
Platelets, which help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken. Platelets are also called thrombocytes.Red blood cells, which carry oxygen. Of the 3 types of blood cells, red blood cells are the most plentiful. In fact, a healthy adult has about 35 trillion of them. The body creates these cells at a rate of about 2.4 million a second, and they each have a life span of about 120 days. Red blood cells are also called erythrocytes.White blood cells, which ward off infection. These cells, which come in many shapes and sizes, are vital to the immune system. When the body is fighting off infection, it makes them in ever-increasing numbers. Still, compared to the number of red blood cells in the body, the number of white blood cells is low. Most healthy adults have about 700 times as many red blood cells as white ones. White blood cells are also called leukocytes.
