Mitosis/Meiosis:Mystery Behind How Nuclear Membrane Forms During Mitosis Solved

Summary: The question of how a dividing cell rebuilds the nuclear envelope has been a controversy for the last 20 years. The answer to this issue is important because the knowledge of the envelope is essential to the further regulation of gene expression. The reformation of the nuclear envelope is the most dramatic event during nuclear assembly.

Questions:Mitosis/Meiosis
What are the differences between mitosis and meiosis? Mitosis is the production of a single from cell from two parent cells; Meiosis is the process of comprising two successive nuclear divisions with only one round of DNA.
What problems ca arise if either of these processes is not controlled properly?The body may not functon correctly
List three things you learned from this article in your own words.
1.This issue has been a mystery for 20 years
2.Mitosis and meiosis are very dissimilar
3. Mitosis and meiosis are two kinds of processes
What impact would the absence of this process have on the cell? Cells could not divide successfully
