1. Mitosis and Meiosis
Summary

2. Cell Reproduction Summary
Prokaryotic Cell Reproduction
Binary Fission
Conjugation
Eukaryotic Cell Reproduction
(reproduction of the nucleus)
Mitosis
Meiosis
After mitosis and meiosis occur then the cell itself divides and this is called cytokinesis

3. Mitosis The division of eukaryotic cells
The goal of mitosis is to produce two cells that are genetically identical to the parent cell, meaning the new cells have exactly the same DNA as the parent cell. Fore example, mitosis happens when you grow.

4. Meiosis The division of eukaryotic cells
The goal of meiosis is to produce sperm or eggs cells, also known as gametes. The resulting gametes are NOT genetically identical to the parent cell. The new cells have only half of the parent cell’s This is necessary so that when a sperm and an egg combine at fertilization, the resulting zygote has the correct amount of DNA. The zygote then begins to divide through mitosis.

5. Cell Cycle (Mitosis)

6. Cell Biology (Mitosis)
All living organisms are composed of cells.
Cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes.

8. The Complete Cell Cycle

9. Chromosome Structure
Centromere

10. Chromosome Structure So 1 chromatid + 1 chromatid = 1 Chromosome

11. Interphase THE CELL: grows to it’s mature size
makes a _____ of its DNA
prepares to _______ into two cells
Copy
Divide

12. The DNA condenses

13. Prophase the nucleus breaks down
Chromatin
the __________ condenses (gets thicker) to form chromosomes, which are two chromatids attached by a ____________.
_______ fibers stretch out to opposite ends of the cell
the nucleus breaks down
Centromere
Spindle

14. Metaphase the __________ line up in the middle of the cell
spindle fibers attach to the __________ of the chromosomes
Chromosomes
Centromere

15. Anaphase ____________ split and the chromatids separate
Centromeres
____________ split and the chromatids separate
chromatid to opposite ends of the cell being pulled by the ___________
the cell begins to become stretched out
Spindle Fibers

16. Telophase the __________ reappears – two nuclei but one cell
chromosomes begins to loosen up (start to become string again)
Nucleus

17. Cytokinesis the cell divides and two new ___________ cells are formed
chromosomes loosen up and become chromatin again
Daughter
