Final answer:
Prokaryotes have a single, circular chromosome and eukaryotes have multiple, linear chromosomes, with different mechanisms for DNA packaging.
Step-by-step explanation:
The correct answer to the question is b) Prokaryotes have a single, circular chromosome, while eukaryotes have multiple, linear chromosomes. Prokaryotes compact their DNA by supercoiling, with the help of an enzyme called DNA gyrase. Eukaryotic chromosomes are composed of DNA wrapped around histone proteins, which form a complex called chromatin. Eukaryotic cells have structures called heterochromatin, which is not found in prokaryotic cells. The presence or absence of specific chromosomal features distinguishes the intricate mechanisms orchestrating genetic information in prokaryotic and eukaryotic realms.
