**Step-by-Step Solution:** 1. **Understanding Chromatin Structure**: - The nucleus of a cell contains chromatin, which is a complex of DNA and proteins. Chromatin can exist in two forms: euchromatin and heterochromatin. - Chromatin is the less condensed form of DNA, while chromosomes are the highly condensed form. 2. **Differentiation of Chromatin Types**: - **Euchromatin**: This form of chromatin is loosely packed. The DNA strands are more spread out, allowing for easier access for transcription machinery. This results in euchromatin appearing lighter when stained. ...
