Question

Which of the following processes of mitosis is not correct?

a. Prophase → Two chromosomes of DNA are formed, the nuclear membrane breaks down, spindle fibers start to form, centrioles move to opposite poles of the cell
b. Metaphase → Spindle fibers move the chromosomes to the center of the cell
c. Anaphase → Spindle fibers pull the chromatids to opposite ends of the cell, spindle fibers lengthen which causes the cell to elongate
d. Telophase → Nuclear envelopes are made, two new nuclei form, furrow begins to form across the midline of the parent cell
e. None of the above

Answer 1

All the processes of mitosis listed in the student's question are correct. The stages such as prophase, metaphase, anaphase, and telophase are described accurately, leading to the conclusion that 'e. None of the above' is the correct answer.

Step-by-step explanation:

The processes of mitosis described in the student's question are all correct. To clarify:

• Prophase – Chromatin condenses into chromosomes, the nuclear envelope disintegrates, spindle fibers form, and centrioles move to opposite ends of the cell.
• Metaphase – Chromosomes are aligned at the metaphase plate by the spindle fibers.
• Anaphase – Chromatids are pulled apart by spindle fibers to opposite ends of the cell, and the cell elongates.
• Telophase – Nuclear envelopes reform around the two sets of chromosomes, and the cell begins to divide through the process of cytokinesis.

Therefore, the correct answer to the question is e. None of the above, as all the processes listed are accurate representations of the stages of mitosis.

Answer 2

All the descriptions of the mitosis stages provided in the options are accurate; hence the correct answer is 'e. None of the above.'

Step-by-step explanation:

The question is asking which of the listed processes of mitosis is not correct. The stages mentioned are prophase, metaphase, anaphase, and telophase, which are all correct descriptions of what happens in each stage of mitosis.

Therefore, the mentioned correct option in the final answer is e. None of the above. During prophase, chromosomes form and the nuclear envelope disintegrates, while spindle fibers form as centrioles move to opposite poles. In metaphase, chromosomes are aligned at the center of the cell by spindle fibers. Anaphase sees the separation of chromatids moving to opposite ends of the cell.

Telophase involves the reformation of nuclear envelopes and the beginning of cytokinesis. All these descriptions are accurate, and there is no incorrect process listed.
