It helps to package eukaryotic DNA into the nucleus. In DNA packaging, The beads on string arrangement of nucleosomes is approximately 10nm thickness, which is condensed to produce a solenoid of a 30nm diameter. Thus, Option B is correct.

WebTwo principal models exist- the solenoid model and the zig-zag. Finally, further successive folding events lead to a high level of organization and specific domains in the nucleus. … dyox twitterWebH1 protein is responsible for linking two octamers. This nucleosome combines to form a solenoid. The solenoid defines the packing of DNA as a 30 nm fibre of chromatin and results from the helical winding of at least 5 nucleosome strands. This solenoid is coiled and supercoiled to form a compact structure which can be packaged inside the nucleus. dypa thlWebSolenoid model.
