Why is it important that a cell's DNA is duplicated before cell division?

• A. To ensure that each daughter cell receives a complete set of genetic information
• B. To allow the cell to grow larger before dividing
• C. To prevent the cell from undergoing apoptosis
• D. To increase the cell's energy reserves for division

Answer: (A)

Verified step by step guidance

1. Understand the process of cell division: Cell division is the process by which a parent cell divides into two daughter cells. This is essential for growth, repair, and reproduction in living organisms.
2. Recognize the role of DNA in cell division: DNA contains the genetic instructions necessary for the functioning and development of cells. Each daughter cell must receive a complete set of genetic information to function properly.
3. Learn about DNA replication: Before a cell divides, its DNA is duplicated during the S phase of the cell cycle. This ensures that each daughter cell inherits an identical copy of the genetic material.
4. Connect DNA duplication to genetic consistency: Without DNA duplication, daughter cells would receive incomplete or unequal genetic information, leading to errors in cellular function or development.
5. Eliminate incorrect options: The correct answer is 'To ensure that each daughter cell receives a complete set of genetic information.' The other options do not accurately describe the purpose of DNA duplication before cell division.
