Question

I'm confused on 1. And 2.

ww Sameness and Variety (Mitosis and Meiosis) 165 EXERCISE #3 "Asexual Reproduction of Cells-Mitosis" Asexual reproduction of cells is called mitosis. Immediately before this cell division process begins, the DNA of a cell (either haploid or diploid) duplicates itself creating two identical copies of molecule (and chromosome). The DNA copies move to opposite ends of the cell. Then the cell partitions itself into two cells (each with exactly the same DNA as the original cell). The purpose of asexual reproduction by mitosis is to create new cells that are genetically identical to the original Mitosis produces every DNA more of the same. cell. Haploid mitosis does happen in some organisms, but will be covered in a more advanced biology course. Diploid Mitosis 2n (2n 2n 2n 1. Let's imagine what would happen to the amount of DNA material in a cell if, when it reproduced, it did not duplicate the DNA first. Complete this cell box. Problem (½n (2n (2n u 2. Explain what this mistake creates in the new cells. For a dividing cell to maintain its original set # in the new cells, it must duplicate its genetic material prior to beginning mitosis. In addition, the genetic material must be divided in such a way that no new cell is missing any DNA, or has more DNA than the original cell. In Conclusion Whatever amount of DNA the original cell has prior to mitosis, its offspring cells will have the same amount after the process is complete.
