The correct response is histones. Histones are the proteins that help package and compress eukaryotic DNA into chromosomes, allowing it to fit within the nucleus.

Responses
Prokaryotic chromosomes are wrapped into structures called nucleosomes.
Prokaryotic chromosomes are wrapped into structures called nucleosomes.
Prokaryotes tend to only have one chromosome while eukaryotes have many.
Prokaryotes tend to only have one chromosome while eukaryotes have many.
Prokaryotic chromosomes are typically much larger than eukaryotic ones.
Prokaryotic chromosomes are typically much larger than eukaryotic ones.
Prokaryotic chromosomes are linear while eukaryotic chromosomes are circular.
Responses
Prokaryotic chromosomes are wrapped into structures called nucleosomes.
Prokaryotic chromosomes are wrapped into structures called nucleosomes.
Prokaryotes tend to only have one chromosome while eukaryotes have many.
Prokaryotes tend to only have one chromosome while eukaryotes have many.
Prokaryotic chromosomes are typically much larger than eukaryotic ones.
Prokaryotic chromosomes are typically much larger than eukaryotic ones.
Prokaryotic chromosomes are linear while eukaryotic chromosomes are circular.
The correct response is Prokaryotes tend to only have one chromosome while eukaryotes have many. Prokaryotic cells typically have a single circular chromosome, while eukaryotic cells have multiple linear chromosomes.
Which answer choice below correctly describes the structure of DNA?(1 point)
Responses
Sugar-nitrogen base backbone with phosphates in the middle forming a double helix.
Sugar-nitrogen base backbone with phosphates in the middle forming a double helix.
A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
Nitrogen bases on the outside with sugar-phosphate in the middle of a double helix.
Nitrogen bases on the outside with sugar-phosphate in the middle of a double helix.
Sugar-phosphate backbone with nitrogen bases coming off a single helix.
Responses
Sugar-nitrogen base backbone with phosphates in the middle forming a double helix.
Sugar-nitrogen base backbone with phosphates in the middle forming a double helix.
A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
Nitrogen bases on the outside with sugar-phosphate in the middle of a double helix.
Nitrogen bases on the outside with sugar-phosphate in the middle of a double helix.
Sugar-phosphate backbone with nitrogen bases coming off a single helix.
The correct response is A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix. This accurately describes the structure of DNA, where the sugar and phosphate molecules form the outer backbone, while the nitrogen bases pair in the center.
