Mitosis Tutorial
1. Which stage does the following occur
Chromatin condenses into chromosomes
Prophase
Chromosomes align in center of cell.
Metaphase
Longest part of the cell cycle.
Interphase
Nuclear envelope breaks down.
Prometaphase
Cell is cleaved into two new daughter cells.
Anaphase
Daughter chromosomes arrive at the poles.
Telophase
Chromatin condenses into chromosomes
Prophase
Chromosomes align in center of cell.
Metaphase
Longest part of the cell cycle.
Interphase
Nuclear envelope breaks down.
Prometaphase
Cell is cleaved into two new daughter cells.
Anaphase
Daughter chromosomes arrive at the poles.
Telophase
The colored chromosomes represent chromatids. There are two of each color because one is an exact duplicate of the other.
How many chromosomes are visible at the beginning of mitosis? 8
How many are in each daughter cell at the end of mitosis? 4
The little green T shaped things on the cell are: centrioles
What happens to the centrioles during mitosis? They will divide after the DNA replicates.
3 . Identify the stages of these cells:
Telophase
Metaphase
Prophase

(I tried to put the boxes in but it didn't really work!)
Prophase- The nucleus is in the center of the cell, and the chromosomes are in the middle of the nucleus.
Metaphase- The centrioles are being pulled to the opposite sides. There are also many spindle fibers connected to the centrioles and the chromosomes are in the middle.
Telophase- The chromosomes are in V shapes and the spindle fibers are connected to the centrioles.
Prophase- The nucleus is in the center of the cell, and the chromosomes are in the middle of the nucleus.
Metaphase- The centrioles are being pulled to the opposite sides. There are also many spindle fibers connected to the centrioles and the chromosomes are in the middle.
Telophase- The chromosomes are in V shapes and the spindle fibers are connected to the centrioles.

How I became a happy woman again
ReplyDeleteWith tears of joy and happiness i am giving out my testimony to all viewers on line, my problem with Stomach Cancer stage IB has caused me many pains and sadness especially in my family.
I was so afraid of loosing my life, I suffered the embarrassment of visiting
