Answer:
A is called Prophase
B is called Anaphase
C is called Metaphase
D is called Telophase
Explanation:
These can get confusing but I'll explain it for you.
The first stage of <u>mitosis</u> is Prophase.
- In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.
The second stage of <u>mitosis </u>is Metaphase.
- In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.
The third stage of <u>mitosis</u> is Anaphase.
- In this stage the sister chromatids separate into individual chromosomes and are pulled apart.
The fourth and last stage of <u>mitosis</u> is Telophase.
- During this stage the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.
The process that follows the last stage of mitosis is called <u>Cytokinesis</u>.
- With two complete copies of the DNA now in two different regions of one cell, the cell membrane will pinch and divide the cytoplasm in half. The result is two individual cells that are identical to the original cell. Each of the two new cells have a complete copy of the DNA and contain all of the organelles that the original cell had.
Hopefully, this eases the problem for you and you understand it better.
