Concept:
- Cell division is a complex process that involves several phases to ensure accurate replication and distribution of the cell's genetic material.
- The cell cycle is divided into interphase and mitotic phase (M phase). Interphase is further subdivided into G1, S, and G2 phases.
- During the G1 phase, the cell grows and performs its normal functions. It has not yet begun to replicate its DNA.
- The S phase is when DNA replication occurs, ensuring that each daughter cell will have a complete set of chromosomes.
- G2 phase is the period after DNA replication; the cell continues to grow and prepares for mitosis.
- The mitotic phase (M phase) includes mitosis and cytokinesis, leading to the formation of two daughter cells.
Explanation:
- G1: This is the phase when a newly formed daughter cell grows and performs its normal functions. It has not yet replicated its DNA. This is the correct answer as it matches the description provided in the question.
- S: This phase is characterized by DNA replication. During this phase, the cell synthesizes a complete copy of its DNA in preparation for cell division. Since the question specifies that the daughter cell has not yet replicated its DNA, this option is incorrect.
- G2: This phase occurs after DNA replication. The cell continues to grow and prepares for mitosis. Since the DNA has already been replicated by this stage, this option is incorrect
