Question

Which is the correct order of DNA packaging?

Nucleosome $\to$ Chromatid $\to$ Solenoid Fiber $\to$ Chromosome
Nucleosome $\to$ Solenoid Fiber $\to$ Chromatid $\to$ Chromosome
Chromatid $\to$ Solenoid Fiber $\to$ Nucleosome $\to$ Chromosome
Solenoid Fiber $\to$ Nucleosome $\to$ Chromatid $\to$ Chromosome

hint Hint:

DNA -- solenoid fibre -- chromatid -- chromosome

The correct answer is: Nucleosome $rightwards arrow$ Solenoid Fiber $rightwards arrow$ Chromatid $rightwards arrow$ Chromosome

DNA (2 nm); nucleosome (10 nm); solenoid fibre (30 nm); chromatid (700 nm); chromosome (1400 nm)
