Are nucleosomes and chromatin the same?

Chromatin:

1. It is a macromolecule consisting of DNA, RNA, and associated proteins.
2. Chromatin is present in eukaryotic cells' nuclei.
3. Helps in fitting genetic material into cells.
4. They also control gene expression.

Nucleosomes:

1. They are repeating units of chromatin.
2. They appear as "beads on strings" when observed under an electron microscope.
3. Therefore, nucleosomes & chromatin are not the same.
