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 prevent the cell from undergoing apoptosis.
C
To ensure that each daughter cell receives an identical set of genetic information.
D
To allow the cell to produce more energy during division.
Verified step by step guidance1
Understand the process of cell division: Cell division is a fundamental process where a single cell divides into two daughter cells. This process is crucial for growth, development, and repair in multicellular organisms.
Recognize the role of DNA in cell division: DNA contains the genetic blueprint of an organism. It is essential that this genetic information is accurately passed on to the daughter cells during cell division.
Identify the phase where DNA duplication occurs: DNA duplication occurs during the S phase (Synthesis phase) of the cell cycle, before the cell enters mitosis or meiosis.
Explain the importance of DNA duplication: By duplicating its DNA before division, the cell ensures that each daughter cell receives an identical set of genetic information. This is crucial for maintaining the integrity and function of the organism.
Consider the consequences of not duplicating DNA: If DNA is not duplicated, daughter cells would receive incomplete or incorrect genetic information, leading to malfunction or cell death, and potentially causing diseases such as cancer.
