Molecular Structure of Chromosomes According to the recent and widely accepted theory of Dupraw (1965, 1970) and Hans Ris (1967) called unistranded theory, each eukaryotic chromosome is composed of a single, greatly elongated and highly folded nucleoprotein fibre of 100A . 196,10 (2014): 1793-806. The cell cycle and mitosis. The sequence of bases within a DNA molecule represents the genetic information of the cell. Ø DNA in the chromatin attain a packing ratio of about 7:1 (seven fold packing) by the formation of nucleosomes.. Ø Nucleosome units organized into more compact structure of 30 nm in diameter called 30 nm fibers (proposed by Rachel Horowitz & Christopher Woodcock in 1990)..
