Answer:

e) Bacteria have no histones associated with their chromosomes and the other two groups do.

Explanation:

Eukaryotes are the organisms that have membrane bound nucleus.

Prokaryotes don't have membrane bound nucleus.

Archaea and bacteria are prokaryotes.

Bacteria contain peptidoglycan in their cell wall while Archaea and Eukaryotes usually don't contain (exceptions like fungi).

Archaea and bacteria usually have circular while eukaryotes usually contain linear DNA.

Bacteria have no histones associated with their chromosomes and the other two groups do.

Explanation:

Bacteria are single celled, microscopic living organism that are found everywhere.

Some bacteria are beneficial I.e they help in fermentation and decomposition while some are harmful by causing diseases.

Bacteria have no his tones associated in their chromosomes compare to Achaea and eukaryotes.

The histones is a protein like found in Eukaryote and Achaea that surround their DNA which help to package the DNA in smaller spaces.

Bacteria lack histones because their DNA is circular but their DNA is packaged by DNA binding proteins. Bacteria compress their DNA into smaller spaces by supercoiling.
