d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome
Explanation:
As we know that the
- Diameter of DNA is 2 nm.
- Diameter of nucleosome is 11 nm.
- Diameter of solenoid is 30 nm.
- Diameter of looped chromation is 300 nm
- Diameter of meta-phase chromosome is 1400 nm
All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.
