Rank the following levels of chromatin compaction in eukaryotes from the least compact to the most compact.
Scilla [17]

Answer:

a. Naked dna

f. nucleosome

e. solenoid

g. loop domain

d. chromatid

c. chromosomes

b. metaphase

Explanation:

The naked DNA consists of the DNA molecule not associated with proteins.

A nucleosome is an octamer of histone proteins (i.e., dimers of H2A, H2B, H3, H4) associated with DNA.

A solenoid is a chromatin fiber consisting of 30 nanometers (nm), it represents the secondary structure of the chromatin.

The chromatin fibers are organized into loops (300 nm) that represent the tertiary structure of the chromatin. These loops enable to package chromosome segments consisting of about 100 kilobases (kb).

The sister chromatids are two identical DNA-based structures that remain joined together by the centromere to form a single chromosome (700 nm).
