A nucleosome typically contains 200 base pairs. On dividing 50 million by 200, one would get 250,000 which would tell about the number of nucleosomes associated with the human Y chromosome.

A nucleosome is a segment of DNA that is wrapped around a core of proteins. A nucleosomes constitutes the repeating unit of a structure in nucleus known as chromatin (thread-like stained bodies present in nucleus).

The nucleosomes in chromatin appear as 'beads-on-string' when viewed under an electron microscope.
