Chromosomes l Diploid contains 2 sets of chromosomes
- Slides: 33
Chromosomes l Diploid: contains 2 sets of chromosomes ¡Body cells, 2 n l Haploid: contains 1 set of chromosomes ¡Gametes, sex cells, n Sister chromatids- 2 identical chromatids held together by a centromere Kinetochores: protein complex that develops on either side of centromere.
Phases of Mitosis l Prophase ¡ Centrosomes have duplicated ¡ Chromatin condenses into chromosomes ¡ Spindles forming ¡ Nucleolus and nuclear envelope disappear l Metaphase ¡ Centromeres/chromosomes aligned along middle ¡ Spindles attach to kinetochore l Anaphase ¡ Sister chromatids are pulled apart and daughter chromosomes move toward opposite poles. ¡ Cleavage furrow begins to form l Telophase ¡ Nuclear envelope and nucleolus reappear. ¡ Chromosomes begin to uncoil
cytokinesis l Division of the cytoplasm l Animal cell ¡Cleavage furrow forms ¡Band of actin filaments (contractile ring), forms a circular constriction l Plant cell ¡Golgi apparatus forms vesicles which move along the microtubules to the region of a small disk seen between the 3 daughter plant cells ¡Cell plate (newly formed plasma membrane) forms between the daughter cells
