Chromatin remodeling is a process that alters the structure of chromatin, the material made of DNA and proteins that forms chromosomes. This remodeling allows access to specific genes, making them available for transcription and other cellular functions. It plays a crucial role in regulating gene expression and maintaining the overall organization of the genome. The remodeling is facilitated by various protein complexes that can reposition, eject, or restructure nucleosomes, the basic units of chromatin. These changes can be influenced by factors such as cell signaling, environmental conditions, and developmental cues, ensuring that the right genes are activated at the right time.
