If the initial amount of DNA is 8 C then after S phase the amount of DNA would be

Options

A. 4 C
B. 8 C
C. 64 C
D. 16 C

Answer

To solve the question regarding the amount of DNA after the S phase, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Initial Amount of DNA**:
- The initial amount of DNA is given as 8C. Here, "C" represents a unit of DNA content.

2. **Identifying the Role of the S Phase**:
- The S phase (Synthesis phase) is a part of the cell cycle where DNA replication occurs. During this phase, the amount of DNA in the cell is doubled.

3. **Calculating the Amount of DNA After S Phase**:
- Since the DNA content doubles during the S phase, we can calculate the new amount of DNA by multiplying the initial amount by 2.
- Therefore, after the S phase, the amount of DNA will be:
\[ 8C \times 2 = 16C \]

4. **Conclusion**:
- After the S phase, the amount of DNA in the cell will be 16C.

### Final Answer:
The amount of DNA after the S phase will be **16C**.
