1. Anaphase

   Anaphase (from Ancient Greek ἀνα- (ana-) 'back, backward', and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell. Chromosomes also reach their overall maximum condensation in late anaphase, to help chromosome segregation and the re-formation of the nucleus.Anaphase starts when the anaphase promoting complex marks an inhibitory chaperone called securin for destruction by ubiquitylating it. Securin is a protein which inhibits a protease known as separase. The destruction of securin unleashes separase which then breaks down cohesin, a protein responsible for holding sister chromatids together.At this point, three subclasses of microtubule unique to mitosis are involved in creating the forces necessary to separate the chromatids: kinetochore microtubules, interpolar microtubules, and astral microtubules. The centromeres are split, and the sister chromatids are pulled toward the poles by kinetochore microtubules. They take on a V-shape or Y-shape as they are pulled to either pole. While the chromosomes are drawn to each side of the cell, interpolar microtubules and astral microtubules generate forces that stretch the cell into an oval.Once anaphase is complete, the cell moves into telophase.

1. anaphase

   Anaphase is a stage in the process of cell division, or mitosis, in which the chromosomes separate and move to opposite ends of the cell. This stage directly follows metaphase and precedes telophase, helping to ensure that each new daughter cell will have the correct number of chromosomes.

1. Anaphase

   Anaphase, from the ancient Greek ἀνά and φάσις, is the stage of mitosis or meiosis when chromosomes are split and the sister chromatids move to opposite poles of the cell. Anaphase accounts for approximately 1% of the cell cycle's duration. It begins with the regulated triggering of the metaphase-to-anaphase transition. Metaphase ends with the destruction of B cyclin. B cyclin is marked with ubiquitin which flags it for destruction by proteasomes, which is required for the function of metaphase cyclin-dependent kinases. Anaphase starts when the anaphase promoting complex marks an inhibitory chaperone called securin with ubiquitin for destruction. Securin is a protein which inhibits a protease known as separase. Once destroyed, separase is unleashed and breaks down cohesin, a protein responsible for holding sister chromatids together. The centromeres are split, and the new daughter chromosomes are pulled toward the poles. They take on a V-shape as they are pulled back. While the chromosomes are drawn to each side of the cell, the non-kinetochore spindle fibers push against each other, in a ratcheting action, that stretches the cell into an oval. Once anaphase is complete, the cell moves into telophase.

1. Anaphase

   Anaphase is the 3rd phase of mitosis which is a process that separates the duplicated genetic material carried in the nucleus of a parent cell into two daughter cells
