which is the correct folding sequence of dna from simplest to most complex?
double helix -> 30 - nm fiber -> nucleosome -> chromosome
nucleosome -> double helix -> 30 - nm structure -> chromosome
double helix -> 30 - nm fiber -> chromosome -> nucleosome
double helix -> nucleosome -> 30 - nm fiber -> chromosome

Explanation:

DNA starts as a double helix. Then, it wraps around histone proteins to form nucleosomes. Nucleosomes further coil to form a 30 - nm fiber. Finally, the 30 - nm fiber undergoes more folding and compaction to form a chromosome.

Answer:

Double helix → Nucleosome→ 30 - nm fiber → Chromosome
