Mitosis - Process of cell division for growth and repair. It produces 2 daughter cells which are identical., Meiosis - The process of cell division to create gametes. It produces 4 haploid daughter cells., Mutation - Change in the base sequence of DNA, Interphase - The largest part of the cell cycle, it is known as the resting phase., Prophase - In this stage chromosomes become visible as they shorten and thicken., Spindle fibres - Centrioles release these which span the cell from pole to pole., Metaphase - In this stage chromosomes are made up of 2 chromatids and arrange themselves on the equator of the cell., Anaphase - In this stage the spindle fibres attach to the centromere and pull chromatids to the opposite poles of the cell., Chromatid - One of the 2 strand of a chromosomes that are joined at the centromere., Centromere - Where the chromatids are joined together, Teleophase - In this stage the chromatids reach their poles and begin to disappear and the nucleus reforms., Cytokinesis - The division of the cytoplasm to create new cells., Binary Fission - This is the process of cell division in bacteria., Haploid - A cell that contains half the number (n) of chromsomes as the parent cell., Diploid - A cell that contains a full set of chromosomes (2n), Cancer - A group of diseases caused by a growth disorder of cells., Cell cycle - The process which cells go through in their life time. It includes- interphase, nuclear division and cytokinesis.,
