PLEAS HELP!! TY 1. What is the overall purpose of mitosis and meiosis?
2. Why is it important that DNA is replicated prior to cell division?
3. How are normal cells and cancer cells different from each other?
4. Describe mistakes that can occur during the cell cycle and cause human disorders.

1. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less. Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs.

2. Cell division is needed to produce large number of cells necessary to form the individual. ... DNA replicates before a cell divides to give a complete set of genetic instructions to each daughter cell.

3. Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.

4. okay I think this is right if not then sorry

Other mistakes that can occur during meiosis include translocation, in which part of one chromosome becomes attached to another, and deletion, in which part of one chromosome is lost entirely.
