Anafaasissa

Anafaasissa is a term used in biology, specifically within the study of cell division, to describe a phase in mitosis or meiosis. During anaphase, the sister chromatids (in mitosis and meiosis II) or homologous chromosomes (in meiosis I) separate and move to opposite poles of the cell. This separation is driven by the shortening of spindle fibers, which are protein structures that attach to the chromosomes. The accurate segregation of genetic material during anaphase is crucial for ensuring that daughter cells receive a complete and correct set of chromosomes. Errors in anaphase can lead to aneuploidy, a condition where cells have an abnormal number of chromosomes, which can have significant consequences for cell function and organismal health. The process is highly regulated by a complex molecular machinery that ensures proper chromosome movement and timely completion of this critical stage of cell division.
