What are the events that take place during telophase of mitosis?
What Happens during Telophase? During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes. Phosphatases then dephosphorylate the lamins at each end of the cell.
What happens during telophase 1 and cytokinesis?
During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
What happens during telophase II of meiosis quizlet?
What happens during telophase II of meiosis? The nuclear membrane begins to form around haploid sets of chromosomes. … Homologous chromosomes separate but sister chromatids remain joined at their centromeres. Meiosis results in genetic variation among its product cells.
What is telophase 2 and cytokinesis in meiosis?
Telophase II is the stage in meiosis II that follows after anaphase II. … This will then be followed by cytokinesis, wherein each of the two cells produced from meiosis I will give rise to two daughter cells, resulting in a total of four genetically dissimilar haploid cells. The chromosomes de-condense and lengthen.
How does segregation happen during anaphase 2?
There are two ways in which non-disjunction can occur: 1) both homologous chromosomes migrate together to one pole instead of separating to opposite poles in Anaphase I or 2) sister chromatids fail to separate properly and both sister chromatids move together to one pole instead of to opposite poles in Anaphase II.
What two processes happen during mitosis?
This process involves replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm.
