Open in App
Solution
The correct option is A Nucleosomes
If the chromatin is subjected to treatments that cause it to unfold partially, it can be seen under the electron microscope as a series of “beads on a string” The string is DNA, and each bead is a “nucleosome core particle” that consists of DNA wound around a protein core formed from histones.So, the correct answer is 'Nucleosomes'.
