Options

A. `68000 Å`
B. `34000Å`
C. `10000Å`
D. Im

Answer

To find the length of DNA containing 10,000 base pairs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of DNA**:
- DNA is structured as a double helix, and each complete turn of the helix has a specific vertical rise.

2. **Know the Rise per Base Pair**:
- Each base pair in DNA contributes to a vertical rise of approximately 0.34 nanometers (or 3.4 Ångströms).

3. **Calculate the Total Length**:
- To find the total length of the DNA, we multiply the number of base pairs by the rise per base pair.
- Formula:
\[ \text{Length of DNA} = \text{Number of Base Pairs} \times \text{Rise per Base Pair} \]
- Plugging in the values:
\[ \text{Length of DNA} = 10,000 \, \text{base pairs} \times 3.4 \, \text{Ångströms/base pair} \]
- Performing the multiplication:
\[ \text{Length of DNA} = 34,000 \, \text{Ångströms} \]

4. **Select the Correct Answer**:
- From the options provided, the correct answer is 34,000 Ångströms.

### Final Answer:
The length of DNA containing 10,000 base pairs is **34,000 Ångströms**.
