This is a freak accident in the mammalian lineage.
You have about 25 trillions of RBC in your blood. They do not have nucleus in them and so no DNA. WBC has a nucleus and contains the DNA.
Yes. Without nuclei, cells have no genes, no ability to synthesize proteins, and therefore to carry out their basic biological functions. All red blood cells ultimately derive from hematopoietic stem cells (HSC) that are located within the bone marrow. The HSCs have nuclei and spawn several kinds of progenitor cells that each give rise to the various types of blood cells. In the RBC lineage, just before the mature RBC is formed, the nucleus is expelled.
1.The absence of nucleus gives space for rbc to accommodates its huge haemoglobin 2.further it is also responsible for biconcave shape of rbcs which helps it to squeeze through the narrow capillaries.
Plant and animal cells are both eukaryotes. However, some animal cells may be prokaryotes, like red blood cells. RBC do not have nucleus. They are considered prokaryotes, so they do not live long.
Nucleus is an imp component of cell essential for survival . An organised nucleus appears in eukaryotes(except mammalian rbc and sieve tube cells of phloem) for the first time .Prokaryotes have an unorganised nucleus....
A frog has a nucleus in matured RBC.
red blood cells that have not lost their nucleus.
a rbc has no nucleus
Yes.
Camel
camels have nucleus in their RBC's.
Nucleus is a large organell.Lackness of a nucleus gives a large space for haemoglobin.
They are cells that have or contain nucleus , as compared to RBC that are enucleated
Though RBC does not have organelles nor Nucleus it can live for about 120 with the help of the enzymes involved in glycolysis reaction , and remember the definition of cell , it is a living unit of life and rbc is living cell
You have about 25 trillions of RBC in your blood. They do not have nucleus in them and so no DNA. WBC has a nucleus and contains the DNA.
Mammalian RBC is always enucleated [Without nucleus] without any EXCEPTION The mammalian RBC is also biconcave and DISCOIDAL except Camel and Llama, which have Oval shaped RBC
i believe, and this is only a guess, because the outer nuclear membrane forms a continuum with the rough endoplasmic reticulum, when the nucleus is lost, so is the ER
