The amount of DNA that is associated with each nucleosome is a approximately 200 bp. This is determined by treating chromatin wwith a certain enzyme that cuts DNA. This enzyme is called DNases. Every chromosome has hundred of thousands of nucleosomes that are joined by DNA strands that pass between them.
When cells communicate by the signaling process, one cell produces a signaling molecule that must be received by the signal receptor on or in the responding cell. Signaling molecules are often called ligands, a general term for molecules that bind specifically to other molecules (such as receptors).
