The two cells formed during mitosis contain

Options

A. same amount of DNA and same set of chromosomes as those of parent cell.
B. same amount of DNA and different set of chromosomes as those of parent cell.
C. half amount of DNA and same set of chromosomes as those of parent cell.
D. double amount of DNA and same set of chromosomes as those of parent cell.

Answer

**Step-by-Step Solution:**

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two identical daughter cells from a single parent cell. It is often referred to as equational division because the daughter cells have the same number of chromosomes as the parent cell.

2. **Chromosome Number**: In mitosis, the chromosome number remains constant. If the parent cell is diploid (2n), the daughter cells will also be diploid (2n). This means that the set of chromosomes in the two daughter cells is identical to that of the parent cell.

3. **DNA Content**: Before mitosis, during the S phase of the cell cycle, the DNA content of the parent cell doubles. If we denote the initial amount of DNA in the parent cell as 2C, after DNA replication in the S phase, it becomes 4C.

4. **After Mitosis**: Once mitosis is completed, the cell divides into two daughter cells. Each daughter cell will receive half of the DNA content of the parent cell. Therefore, each daughter cell will have 2C of DNA.

5. **Conclusion**: The two cells formed during mitosis will contain the same set of chromosomes as the parent cell but will have half the amount of DNA. Thus, the correct answer is that the two cells formed during mitosis contain the same set of chromosomes and half the amount of DNA compared to the parent cell.

**Final Answer**: The two cells formed during mitosis contain the same set of chromosomes as the parent cell and half the amount of DNA.
