Chromatin Structure

Chromatin is the complex of DNA and proteins found in the nucleus of cells. It helps package DNA into a more organized structure, allowing it to fit inside the cell while also regulating gene expression. Think of chromatin as a spool of thread; the thread represents DNA, and the spool represents proteins called histones that help wind and organize the DNA. This structure changes depending on the cell's needs, making certain genes accessible for activation while keeping others tightly packed away. Proper chromatin structure is vital for cell functions, development, and maintaining genetic stability.
