The correct comparison between prokaryotic and eukaryotic chromosomes is:

**Prokaryotes tend to only have one chromosome while eukaryotes have many.**

Prokaryotic chromosomes are typically circular and usually consist of a single chromosome, whereas eukaryotes have multiple linear chromosomes.

The answer choice that correctly describes the structure of DNA is:

**A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.**

In the DNA double helix, the sugar-phosphate backbone is on the outside, while the nitrogen bases are paired in the center.

The combination of DNA and protein in chromosomes is called:

**nucleosomes**

Nucleosomes consist of DNA wrapped around histone proteins, which help in the packaging of DNA into chromosomes.
