Question

How do the daughter cells at the end of mitosis and cytokinesis, compare with their parent cell when it was in G${}_1$ of the cell cycle?

• A. The daughter cells have half the amount of cytoplasm and half the amount of DNA
• B. The daughter cells have half the number of chromosomes and half the amount of DNA
• C. The daughter cells have the same number of chromosomes and half the amount of DNA
• D. The daughter cells have the same number of chromosomes and same amount of DNA

Answer 1

The correct option is D The daughter cells have the same number of chromosomes and same amount of DNA

The DNA is replicated in the S-phase of interphase which takes place before mitotic phase. Two copies of the DNA are synthesized and distributed into the two daughter cells which are formed after mitotic division. The mitosis is the equational division in which the parent cell and the daughter cells contain the same amount of DNA and number of chromosomes.

Thus, the correct answer is option D.
