What process occurs during anaphase?
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. … During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes.
Which describes the events that occur during anaphase II?
As anaphase II proceeds sister chromatids are separated and are pulled toward the pole to which they are attached. During telophase II, sister chromatids reach their respective poles and decondense; nuclear membrane re-forms and nucleoli reappear.
What happens during prophase metaphase anaphase and telophase?
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister …
Which processes has steps called prophase metaphase anaphase and telophase?
Mitosis consists of five morphologically distinct phases: prophase, prometaphase, metaphase, anaphase, and telophase. Each phase involves characteristic steps in the process of chromosome alignment and separation.
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 happens during anaphase II of meiosis quizlet?
What happens during anaphase II of meiosis? Sister chromatids separate from each other and migrate to opposite ends of the cell. … Homologous chromosomes separate but sister chromatids remain joined at their centromeres. Meiosis results in genetic variation among its product cells.
