Question

Which phase of mitosis is essentially the reverse of prophase in terms of nuclear changes?

• A. S - phase
• B. Anaphase
• C. Telophase
• D. Interphase

Answer 1

The correct option is C Telophase

During telophase of mitosis viscosity of cytoplasm decreases. A new nuclear membrane is formed (either from older nuclear envelope or ER) around each set of chromosomes. Chromosomes overlap farming chromatin. The nucleolar organiser region of satellite chromosomes produce nucleolus for each daughter nucleus. Nucleoplasm surrounds in the area of chromatin. The gel state of spindle is converted into sol state and disappears. In this way two daughter nuclei are formed at the poles of spindle. Hence this phase is just reverse of prophase.

So, the correct answer is 'Telophase'.
