Question

Genetically speaking, prokaryotes are different from eukaryotes because:

a. prokaryotes usually have a single circular chromosome, whereas eukaryotes have multiple linear chromosomes.
b. prokaryotes do not usually have histone proteins to package their DNA.
c. prokaryotes do not have a nucleus to maintain their DNA, whereas eukaryotes do.
d. prokaryotes have less total DNA than do eukaryotes.
e. All of the above.

Answer 1

Prokaryotes have a circular chromosome, while eukaryotes have multiple linear chromosomes. Eukaryotes use histone proteins to package their DNA, unlike prokaryotes. Prokaryotes lack a nucleus to maintain their DNA, whereas eukaryotes have a nucleus.

Step-by-step explanation:

Prokaryotes have a single, circular chromosome, while eukaryotes have multiple, linear chromosomes. Eukaryotes pack their chromosomes by super coiling, managed by DNA gyrase.

Prokaryotes chromosomes are wrapped around histone proteins that could form heterochromatin, which is not present in eukaryotes.
