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

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
Guida verificata passo dopo passo1
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.
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.
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.
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.
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.
