Question

mitosis: evaluate the statements
which statement is not true about mitosis?
multiple choice
mitosis is a process that duplicates and divides the nuclear contents only.
mitosis uses a diploid (2n) parent cell to form daughter cells containing a haploid number(n) of chromosomes.
mitosis is involved in development of a fertilized egg into a multicellular organism.
mitosis produces two daughter cells that contain the same number of chromosomes as the parent cell.
mitosis produces two daughter cells that contain the same kinds of chromosomes as the parent cell.

Explanation:

• Mitosis is a process that duplicates and divides the nuclear contents and also divides the cytoplasm (cytokinesis occurs after mitosis). So the statement "Mitosis is a process that duplicates and divides the nuclear contents only" is incorrect.
• Mitosis uses a diploid (2n) parent cell to form diploid (2n) daughter cells. Meiosis is the process that forms haploid (n) cells from diploid (2n) cells. So the statement "Mitosis uses a diploid (2n) parent cell to form daughter cells containing a haploid number(n) of chromosomes" is incorrect.
• Mitosis is involved in the development of a fertilized egg (zygote) into a multicellular organism as it helps in growth and repair.
• Mitosis produces two daughter cells that contain the same number of chromosomes as the parent cell (diploid if parent is diploid).
• Mitosis produces two daughter cells that contain the same kinds of chromosomes as the parent cell.

Answer:

The statements "Mitosis is a process that duplicates and divides the nuclear contents only" and "Mitosis uses a diploid (2n) parent cell to form daughter cells containing a haploid number(n) of chromosomes" are not true about mitosis.
