Question Answer
Interphase Consists of G1, synthesis and G2. The cells DNA is unravelled and replicated, to double its genetic content. The organelles are replicated, and its ATP content is increased.
PROPHASE: Chromosomes condense, getting shorter and fatter. Centrioles start moving to opposite ends of the cell forming a network of protein fibres called the spindle. The nuclear membrane breaks down and the chromosomes are free in the cytoplasm.
METAPHASE: The chromosomes line up along the equator and become attached to the spindle by their centromere.
ANAPHASE: The centromeres divide, separating each pair of sister chromatids. The spindles contract, pulling the chromatids to opposite poles of the spindle, centromere first which makes the chromosomes appear V-shaped
TELOPHASE: The chromatids reach the opposite poles on the spindle. They uncoil and become long and thin again and are now called chromosomes again. A nuclear envelope forms around each group of chromosomes so there are now 2 nuclei. The cytoplasm divides (cytokinesis) and there are now 2 daughter cells that are genetically identical to the original cell and each other.
