Final answer:
Chromatin remodeling allows a cell to temporarily change the structure of its chromatin in order to regulate gene transcription. This process involves modifying histone proteins and DNA, and can be reversed.
Step-by-step explanation:
Chromatin remodeling allows a cell to temporarily change the structure of its chromatin. This is important for regulating gene transcription and controlling whether genes are turned on or off. Chromatin remodeling involves modifications to histone proteins and DNA, such as acetylation, methylation, and phosphorylation, which can open or close the chromatin and allow or block transcription. These modifications can be reversed, allowing the cell to switch between different chromatin states.
