Question

Nucleosome contains

Only histone protein

Both DNA and histone protein

Only DNA

Both DNA and RNA

Solution

Both DNA and histone protein

A nucleosome is a basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound in sequence around eight histone protein cores. It contains both DNA and histone protein. It is the negatively charged DNA wrapped around the positively charged his octamer. It consists of 200bp of DNA helix.
