Options

A. Half as much as in parent nucleus
B. Same as much as in parent nucleus
C. Twice as much as parent nucleus
D. Highly variable

Answer

To answer the question regarding the quantity of DNA in the nucleus of each daughter cell when compared to the G1 phase of mitosis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Cell Cycle**: The cell cycle consists of several phases, including G1, S, G2, and M phases. The G1 phase is where the cell grows and prepares for DNA replication.

**Hint**: Recall the stages of the cell cycle and their functions.

2. **Identify the G1 Phase Characteristics**: During the G1 phase, the cell has a certain amount of DNA, which is the diploid amount for somatic cells (e.g., in humans, this is 46 chromosomes or 23 pairs).

**Hint**: Remember that G1 is the phase before DNA replication occurs.

3. **Understand the S Phase**: In the S phase, DNA replication occurs, meaning the amount of DNA doubles. So, if the cell had 46 chromosomes in G1, after the S phase, it will have 92 chromosomes (46 pairs).

**Hint**: Focus on the fact that DNA replication occurs only in the S phase.

4. **M Phase (Mitosis)**: During mitosis, the replicated chromosomes are separated into two daughter cells. Each daughter cell will receive an equal amount of DNA.

**Hint**: Mitosis is about dividing the replicated DNA equally between daughter cells.

5. **Compare Daughter Cells to G1 Phase**: After mitosis, each daughter cell will have the same amount of DNA as the original parent cell had in the G1 phase. Therefore, each daughter cell will have 46 chromosomes (23 pairs).

**Hint**: Think about how mitosis maintains chromosome number.

6. **Conclusion**: Thus, when compared to the G1 phase of mitosis, the quantity of DNA in the nucleus of each daughter cell will be the same as that of the parent nucleus.

**Final Answer**: The quantity of DNA in each daughter cell will be the same as that of the parent nucleus.

### Summary of the Answer:
The correct answer is that the quantity of DNA in the nucleus of each daughter cell will be the **same as that of the parent nucleus**.
