Question

What happens to chromosomes towards the start of telophase?

Answer 1

Mitosis:

1. Mitosis is the stage of the cell cycle in which freshly generated DNA is separated and two new cells with the same number and type of chromosomes as the parent nucleus are created.
2. Based on the physical condition of the chromosomes and spindle, mitosis is thought to have five stages.
3. Prophase, prometaphase, metaphase, anaphase, and telophase are the stages in mitosis.
4. Cytokinesis is the final physical cell division that occurs after telophase and is thus sometimes regarded as a sixth mitotic phase.

Telophase:

1. The fifth and final step of mitosis occurs when the duplicated genetic material contained in the nucleus of a parent cell is split into two identical daughter cells.
2. It begins when duplicated, paired chromosomes are divided and driven to opposing cell edges, or poles.
3. During telophase, the chromosomes continue to decondense, the spindle disintegrates, and the nuclear membranes and nucleoli re-form.
4. Telophase begins as anaphase comes to an end.
5. During anaphase, the chromosomes or chromatids on the metaphase plate are split and driven towards opposing poles.
6. When the chromosomes reach the pole for which they were created, telophase can begin.
7. At the onset of telophase, chromosomes that have reached their respective poles decondense and lose their identity.
