What distinguishes anaphase from telophase?
Understand the Problem
The question is asking about the differences between anaphase and telophase in the context of cell division. It requires an understanding of the processes occurring during these two phases of mitosis.
Answer
In anaphase, sister chromatids separate and move to opposite poles. In telophase, chromosomes reach poles and decondense, nuclear membranes reform.
Anaphase is characterized by the separation of sister chromatids, which are pulled towards opposite poles by the mitotic spindle. Telophase is marked by the arrival of chromosomes at opposite poles, their decondensation into thin strands of DNA, disappearance of spindle fibers, and reformation of the nuclear membrane.
Answer for screen readers
Anaphase is characterized by the separation of sister chromatids, which are pulled towards opposite poles by the mitotic spindle. Telophase is marked by the arrival of chromosomes at opposite poles, their decondensation into thin strands of DNA, disappearance of spindle fibers, and reformation of the nuclear membrane.
More Information
Anaphase is a critical step where genetic material is evenly split between two future cells, while telophase reverses many changes of the previous phases, preparing the cell for cytokinesis.
Tips
It's important not to confuse the chromatid separation in anaphase with chromosome decondensation in telophase as both involve changes in chromosomes but are distinct events.
