- Forming nucleosomes and wrapping them into a 30-nm fiber provide part of the compaction of DNA in chromatin. If the fiber contains about six nucleosomes per 10 nm of length, what is the approximate compaction ratio achieved?A human chromosome (During Mitosis) is 4 µm long but contains 16 mm of DNA. What is the packing ratio?If the DNA of chromosome 1 is fully extended, it will exceed the diameter of the nucleus of a cell by about 15,000 times. Therefore, discuss how DNA is packaged into the cell.
