Before a cell divides, what must occur?
A
Duplicating the cell's organelles
B
Replicating the cell's genome
C
Duplicating enzymes needed for cellular division
D
All of the above must occur before a cell can divide
Verified step by step guidance1
Understand that cell division is a complex process that requires preparation to ensure each daughter cell receives the necessary components to function properly.
Recognize that the cell's genome must be replicated. This ensures that each daughter cell receives an identical set of genetic instructions. The process of DNA replication occurs during the S phase of the cell cycle.
Acknowledge that organelles must be duplicated. Organelles such as mitochondria and ribosomes need to be present in sufficient numbers to support the metabolic needs of the daughter cells.
Consider that enzymes required for cellular division must be synthesized. These enzymes are crucial for processes such as mitosis and cytokinesis, which physically divide the cell and its contents.
Conclude that all these processes—genome replication, organelle duplication, and enzyme synthesis—are essential for successful cell division, ensuring that each daughter cell is equipped to survive and function.
