Bio Final

• The Mitosis phases are interphase, prophase, metaphase, anaphase, and telophase
• Interphase - the cell grows and develops DNA
• Prophase - Chromatin fiber turns into chromosones
• Metaphase - Microtubules align at centers of chromatid pairs at metaphase plate
• Anaphase - pairs of chromatid separate at centromere and move to opposite ends of cell, becoming chromosomes
• Telophase - two identical nuclei form around chromosomes back in chromatin form
• The phases of Meiosis are Prophase I, Metaphase I, Anaphase I, Telephase I and Cytokenesis, Prophase II, Metaphase II, Anaphase II, Telophase II and Cytokenesis
• Prophase I - Chromatids match with homologous pair and fasten in group of 4 (tetrad)
• Metaphase I - pair of chromosomes line up at metaphase plate
• Anaphase I - Chromosomes separate to opposite poles of cell
• Telephase I and Cytokinesis - Chromosomes gather at poles of cell, and cytoplasm divides into 2 daughter cells
• Prophase II - spindles form around daughter cell
• Metaphase II - chromosomes line up at metaphase plate
• Anaphase II - centromeres separate, chromatids move toward opposite poles
• Telophase II and Cytokinesis - Nuclei form opposite poles and cytokinesis occurs, and 4 daughter cells are created
