Study Notes
Mitosis and Meiosis
-
Prophase (Mitosis): Chromosomes condense and become visible under a microscope. The nuclear membrane breaks down. Spindle fibers begin to form.
-
Prophase (Meiosis I): Chromosomes condense and become visible under a microscope. The nuclear envelope breaks down. Spindle fibers form. Homologous chromosomes pair up.
-
Prophase (Meiosis II): Chromosomes condense and become visible under a microscope. The spindle fibers attach to the chromosomes.
-
Metaphase (Mitosis): Chromosomes align along the metaphase plate (center of the cell).
-
Metaphase (Meiosis I): Paired homologous chromosomes align at the metaphase plate.
-
Metaphase (Meiosis II): Individual chromosomes align at the metaphase plate.
-
Anaphase (Mitosis): Sister chromatids separate and move towards opposite poles of the cell.
-
Anaphase (Meiosis I): Homologous chromosomes separate and move towards opposite poles of the cell.
-
Anaphase (Meiosis II): Sister chromatids separate and move towards opposite poles of the cell.
-
Telophase (Mitosis): Chromosomes decondense. Nuclear membranes reform. Spindle fibers break down. Cytokinesis occurs (division of the cytoplasm).
-
Telophase (Meiosis I): Chromosomes arrive at the poles. Nuclear membranes may reform. Cytokinesis may occur.
-
Telophase (Meiosis II): Chromosomes decondense. Nuclear membranes reform. Spindle fibers break down. Cytokinesis occurs.
-
Mitosis Outcome: Two identical diploid daughter cells are created.
-
Meiosis Outcome: Four haploid daughter cells are created, each with different genetic material.
Chromosome Numbers
-
Mitosis: Starts with 2n chromosomes and ends with two 2n daughter cells.
-
Meiosis I: Starts with 2n chromosomes and ends with 2n cells.
-
Meiosis II: Starts with 2n chromosomes and ends with 4 n cells.
-
2n: Diploid
-
n: Haploid
Key Differences
-
Mitosis: Used for cell growth and repair in all somatic cells and one cell division.
-
Meiosis: Used for sexual reproduction in germ cells and two cell divisions.
