Chromosome sister

WebMay 16, 2024 · After DNA replication in the parent cell, each chromosome is composed of two identical sister chromatids. During the anaphase stage of mitosis, these chromatids separate, and one chromatid goes into each daughter cell. However, when nondisjunction occurs, the chromatids do not separate. WebAug 8, 2024 · During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell, pulled by microtubules. In nondisjunction, the separation fails to occur causing both sister chromatids or homologous chromosomes to be pulled to one pole of the cell.
