FC: Adventures of cells | by: kiya powers

1: table of contents interphase pg 2 first growth pg 3 synthesis pg 4 second growth pg 5 mitosis pg 6 phases of mitosis pg 7-10 cytokensis pg 11

2: interphase | interphase is made up of 3 stages g1, g2, and synthesis. A cell usually spends about 80% of its time in interphase

3: first growth | During this stage new organelles are being synthesized, so the cell requires both structural proteins and enzymes, resulting in great amount of protein synthesis and a high metabolic rate in the cell

4: synthesis | is the part of the cell cycle in which DNA is replicated

5: second growth | the cell’s chromatin condenses into chromosomes and the nuclear envelope begins to break down.

6: mitosis | prophase anaphase metaphase telophase

7: prophase | the two chromatids remain attached to one another at a region called the centromere, but each contracts into a compact tightly coiled body; the nucleolus and, in most cases, the nuclear envelope break down and disappear.

8: anaphase | the two chromatids of each chromosome separate and move to opposite poles, as if pulled along the spindle fibers by the centromeres.

9: The chromosomes congregate at a plane midway between the two ends to which the spindle tapers. | metaphase

10: New nuclear envelopes form around the two groups of daughter chromosomes (as they are now called), the new nucleoli begin to appear, and eventually, as the formation of the two daughter nuclei is completed, the spindle fibers disappear. | telophase

11: cytokensis | is a very accurate way of distributing identical copies of a large amount of genetic material to two daughter cells.

12: The

13: The end.
