Mitosis and Meiosis
Introduction to Mitosis and Meiosis
Mitosis is the process of cell division. Mitosis goes through four stages.
Meiosis is a process in which the number of chromosomes per cell is cut inhalf thruogh the seperation of homologus chromosomes in diploid cell.
Prophase- making chromosomes
Metaphase- line up in the middle
Interphase- duplication of DNA
46 chromosomes 23 pairs
Basically all the stages
Telophase- 2 nuclei are formed and split apart to form 2 daughter cells
Anaphase- pulled apart
2 more stages !
Prophase 1- Each replicated chromosome pairs with its corresponding homologous chromosome.
Metaphase1- Paired homologous chromosomes line up across the center of the cell.
Anaphase 1- Spindle fibers pull each homologous chromosome pair toward opposite ends of the cell.
Telophase 1- A nuclear membrane forms around each cluster of chromosomes, forming two new cells.
Prophase 2- The chromosomes (each consisting of two chromatids) become visible.
Metaphase 2- Chromosomes line up in the center of each cell.
Anaphase 2- The paired chromatids seperate.
Telophase 2- Four haploid daughter cells are formed.
