Complete the given flow chart about DNA compaction and packaging by selecting the correct option. DNA - Chromatin fiber - Chromosome

Assertion :- Positively charged histone proteins are essential for packaging negatively charged DNA. Reason : Without histone protein DNA can not fold due to negative charge.

The length of a DNA molecule in a typical mammalian cell is calculated to be approximately 22 metres. How is the packaging of this long molecule done to accomodate it within the nucleus of the cell ?
