Differentiate between Euchromatin and Heterochromatin.

Explanation

### Step-by-Step Solution:

1. **Definition**:
- **Euchromatin**: It is a loosely packed form of DNA found in chromosomes. This loose packing allows for easier access to the genetic material for transcription and replication.
- **Heterochromatin**: It is a tightly packed form of DNA in chromosomes. This dense packing makes it less accessible for transcription, leading to a more inactive state.

2. **DNA Density**:
- **Euchromatin**: It has low DNA density, meaning that the DNA strands are more spread out.
