they have only one nucleus
DNA is located in the nucleus of most cells of all living organisms. I said most cells because there is no nucleus in red blood cells and no DNA, but all living organisms have a DNA (or RNA) molecule. There are many different types of cells in skeletal bones. Some may have DNA and some may not.
None! A nucleus is in a cell there are no cells in a cell
I don't quite remember all the details, but a bone cell will usually actually have 2 nuclei. The marrow in the bone will produce red blood cells complete with a nucleus, and the red blood cells' nuclei are transferred to the skeletal tissue cells which are also formed with nucleus. I don't remember why though.
No - red blood cells do not contain a nucleus. This means that they cannot replicate, and must therefore be continuosly manufactured in the bone marrow.
Red Blood Cells lack a nucleus. This means they cannot divide. They must be constantly manufactured in the bone marrow to replace those that die.
Red blood cells have nucleus's all throughout Interphase as well as at the end of Telophase during/after Cytokenesis.
No, reticulocytes do not have a nucleus. They are immature red blood cells that still contain some residual RNA when released from the bone marrow. As they mature into erythrocytes (mature red blood cells), the nucleus is extruded.
some members of the order Artiodactyla such as camel
Yes, it is possible for a Eukaryotic cell to have no nucleus. An example of a cell without a nucleus is the mammalian red blood cell. However, Eukaryotic cells without a nucleus, like red blood cells, are unable to replicate. This is why red blood cells need to be continuously produced in the bone marrow.
Kind of cell that does not have a nucleus?
The only cell that I am aware of that does not contain a nucleus is the red blood cell. This cell rely's on specialized cells in the bone marrow in order to reproduce due to the fact that is is a brainless organism.
Nuclei do not contain cells, cells contain nuclei (normally, one nucleus per cell).
