Question

Place the following structures in order based on their packing ratio (from lowest to highest).

-condensed chromosome

-condensed chromatin in the interphase nucleus

-DNA double helix alone (not associated with proteins)

-supercoiled chromatin fibers

-a nucleosome

Answer 1

From lowest to highest:

DNA double helix alone (not associated with proteins).

Supercoiled chromatin fibers.

A nucleosome.

Condensed chromatin in the interphase nucleus.

Condensed chromosome.

DNA coils around a set of for histone protiens, which form a beadlike string known as a nucleosome. The nucleosome coils into structures called chromatin. Chromatin super coils, which form structure of chromosome.
