Summary:Just how a dividing cell rebuilds the nuclear envelope, the protective, functional wrapping that encases both the original and newly copied genetic material, has been a source of controversy for the last 20 years.

Mitosis/Meiosis
What are the differences between mitosis and meiosis?Mitosis -cell division including division of the nucleus and the cytoplasm.Meiosis-cell division in sexually reproducing organisms

What problems can arise if either of these processes is not controlled properly? The cell wont be able to divide.

List three things you learned from this article in your own words.During mitosis, the nuclear envelope disintegrates, The chromosomes are pulled apart and the cell starts to divide,individual tubules of the endoplasmatic reticulum bind directly to chromatin.

What impact would the absence of this process have on the cell?The organsim will die
