Which is the only cell in body of a mammal not to have a nucleus n who is the only mammal to have its nucleus.

red blood cells dont contain a nucleus but i am not sure if it is the only cell. red blood cells dont contain a neucleus so that there is a larger surface area for oxygen to bind with the haemoblobin within the cell. birds dont have a nucleus, to find out why click on the link below.

red blood cells dont hv nucleus n camels n llamas are the only ones to hv nucleated rbcs

RBC or the erythrocyte do not posses nucleus.

All the mammals have enucleated RBC

as the others said mammals have no nuclues in their RBC but only in the ones WHO ARE MATURED.... i mean out of womb and camels on the other hand have nuclues in their matured stage !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!i… it not interesting

"Actually, red blood cells DO have a nucleus, but platelets do not. It's easy to get them confused." Are you serious? I feel sorry for your students. Mature red blood cells DO NOT contain a nucleus. Immature red blood cells, yes.

Erythrocytes, red blood cells, are anucleate in all mammals. The bit about camels having a nucleus is based on early false interpretation of an observation. A researcher perceived that the more oval shape of a camel is indicative of having a nucleus. That made it into the textbooks and was passed on over and over, but has since been disproven repeatedly. Some modern textbooks even contain this falsehood. Camels have no nucleus in their red blood cells. It's a good example about how exciting statements survive (i.e. camels are a crazy exception to the no nucleus rule) when the mundane retractions (i.e. camels are just like everyone else) don't get the same amount of press.
