Solution
A nucleosome is the basic structural unit of DNA packaging in eukaryotes. It is the core particle that consists of approximately 146 base pairs (bp) of DNA.
It appears like a beads on strings under and electron microscope. DNA is negatively charged and is wrapped around positively charged histones. 8 histones surround the DNA to form one nucleosome. This occurs repeatedly throughout the length of the DNA or chromatin.
thus option 1 is incorrect and hence the answer.
