What is a solenoid? Biology Questions - Toppr
WebTwo general models have been proposed for the structure of the 30-nm fiber (see Figure 2.4): Solenoid. The solenoid involves tight interactions between nucleosomes to form a compact, symmetrical structure that resembles a helix. The solenoid form of the 30-nm fiber is advantageous because it allows a high degree of chromosome compaction. how many basketball players on a team
