Multiple Choice
Why is it important that a cell's DNA is duplicated before cell division?
A
To increase the cell's size before division.
B
To ensure that each daughter cell receives an identical set of genetic information.
C
To allow the cell to produce more energy during division.
D
To prevent the cell from undergoing apoptosis.
Verified step by step guidance1
Understand the role of DNA in a cell: DNA contains the genetic instructions necessary for the development, functioning, and reproduction of all living organisms and cells.
Recognize the process of cell division: Cell division is the process by which a parent cell divides into two or more daughter cells. It is essential for growth, repair, and reproduction in organisms.
Identify the importance of DNA duplication: Before a cell divides, it must duplicate its DNA so that each daughter cell receives a complete set of genetic information. This ensures that the daughter cells can function properly and maintain the characteristics of the parent cell.
Consider the consequences of DNA not being duplicated: If DNA is not duplicated before cell division, the daughter cells would not have the necessary genetic information to survive and function, leading to potential cell malfunction or death.
Conclude the necessity of DNA duplication: DNA duplication is crucial for maintaining genetic consistency across generations of cells, allowing for proper growth, development, and functioning of organisms.
