Question

to understand the structure of eukaryotic dna, rank the following from least to most condensed.

rank the options below.

chromatin
supercoiled chromatin
double-stranded dna
chromosome
nucleosome
condensed chromatin

Explanation:

Identify levels of eukaryotic DNA packaging

The levels of DNA packaging from least condensed (simplest structure) to most condensed (highly packaged structure) are:

1. Double-stranded DNA (naked DNA helix, ~2 nm diameter)
2. Nucleosome ("beads-on-a-string" structure, DNA wrapped around histones, ~11 nm diameter)
3. Chromatin (30 nm fiber)
4. Condensed chromatin (looped domains, ~300 nm)
5. Supercoiled chromatin (coiled/folded loops, ~700 nm chromatid)
6. Chromosome (fully condensed metaphase chromosome, ~1400 nm)

Map options to the ranking

• Least condensed (1): Double-stranded DNA
• (2): Nucleosome
• (3): Chromatin
• (4): Condensed chromatin
• (5): Supercoiled chromatin
• Most condensed (6): Chromosome

Answer:

No.	Answer
2	Nucleosome
3	Chromatin
4	Condensed chromatin
5	Supercoiled chromatin
6	Chromosome
