Question

The role of mitosis is not merely, to divide a cell into two daughter cells but to ensure genetic continuity, from one cell generation to another cell generation. The mechanism ensuring genetic continuity is

• A. Formation of cells with new chromosomes
• B. Formation of two daughter cells
• C. Formation of two cells with identical DNA
• D. Halving the chromosome number between the two new cells

Answer 1

Answer: (C)

Formation of two cells with identical 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. This helps to ensure the continuity of the species and the inheritance of the genetic material from one cell to the next generation.

Thus, the correct answer is option C.
