Red cells, at one time contained nuclei; however, when circulating in your blood stream, they do not.
Some types of cells, including red blood cells as an example, do not contain nuclei, or a nucleus. The nucleus is the "brain" of a cell. Both animal and plant cells contain nuclei.
Red blood cells are the only functional cell with no nucleus
bacterial cells do not contain nuclei and are known as prokaryotes. However a special case is red blood cells which do not contain nuclei either and are known as denucleated
Mammalian cells have nuclei. But red blood cells lack
No, fish typically do not have nuclei in their red blood cells. Most mature fish red blood cells are enucleated, meaning they do not contain a nucleus. This allows for more efficient oxygen transport in their bloodstream.
A lack of nuclei allows the red blood cell to contain more hemoglobin, which transports oxygen. It also allows the red blood cells to squeeze through tight spots as they travel the body
red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.
A cow's red blood cell does not have a nuclei. Most mammals do not have a nuclei in their red blood cells.
Reptile red blood cells are nucleated, meaning they contain a nucleus, unlike mammalian red blood cells which are anucleate. Reptile red blood cells are also oval-shaped whereas mammalian red blood cells are typically circular. Additionally, reptile red blood cells contain different types of hemoglobin compared to mammals.
Frog red blood cells contain a nucleus, whereas human red blood cells do not.
All groups of white blood cells have DNA. When a blood sample is procured for the isolation of DNA, the white blood cells are the target cells since they have nuclei containing DNA. Red blood cells on the other hand, contain neither nuclei nor DNA
Because your white blood cells have nuclei - which is where the chromosomes are found. Mature red blood cells do not have nuclei.
