What is the approximate length of DNA in a single human cell?

Answer

To determine the approximate length of DNA in a single human cell, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding DNA**: DNA stands for deoxyribonucleic acid, which is the hereditary material in humans and almost all other organisms. It carries genetic information.

2. **Location of DNA**: In human cells, DNA is located in the chromosomes, which are structures within the cell nucleus.

3. **Structure of DNA**: DNA is a long, double-stranded molecule that is negatively charged. It is tightly packed with proteins known as histones, which help organize and condense the DNA into a compact structure.

4. **Length of DNA in a Cell**: The question specifically asks for the length of DNA in a single human cell. It is estimated that the total length of DNA in one human cell is approximately 2 meters (or about 6.5 feet) when fully extended.

5. **Conclusion**: Therefore, the approximate length of DNA in a single human cell is about 2 meters.

### Final Answer:
The approximate length of DNA in a single human cell is about 2 meters.
