Question

Which of the following is not a stage of mitosis?

• A. Anaphase
• B. Metaphase
• C. Interphase
• D. Prophase

Answer 1

The correct option is C Interphase

• The cell cycle for any cell is divided into 2 phases that are interphase and M phase.
• The M phase is denoted for mitosis or meiosis, here the cell division takes place.
• The interphase is the phase where the G1, S and G2 phase of cell cycle are included. During which the cell grows and rests between the 2 consecutive cell divisions.
• The mitosis cell division is characterized by the presence of 4 phases which are prophase where the condensation of the chromatin takes places and the disappearance of the nuclear membrane.
• Followed by metaphase where the genetic material that is the chromosomes, they are lined at the equatorial plate.
• After which the chromosomes are pulled at the poles of the dividing cell by the spindle fibers attached to their kinetochores which is the characteristic of anaphase.
• The last phase is the telophase where the nuclear membrane starts to appear again and the cytokinesis and karyokinesis takes place.
• Therefore the option 'Interphase' is the correct answer.
