Metaphase histology
WebMetaphase (#1 and #2) - chromosomes line up in the center of the cell; Anaphase (#1, #2, and #3) - chromosomes are pulled to opposite sides of the cells; Telophase (#1 and #2) - chromosomes arrive at the cell poles and will form two nuclei; Practice locating other cells in each stage of mitosis. WebAfter disintegration of the nuclear envelope, the cell is in metaphase. During this phase the completely condensed chromosomes (each pair of sister chromatids) align themselves in …

WebThis is the method by which the body produces new cells for both growth and repair of aging or damaged tissues throughout the body - as opposed to for sexual reproduction (when meiosis applies). Mitosis is the simplest of the two ways (mitosis and meiosis) in which the nucleus of a cell can divide as part of a process of whole cell division ... WebFISH on Metaphase spreads.
