BIOL 207 Chapter 2 Exam Questions with Correct Answers Latest Update 2026/2027
Cells are categorized as either prokaryotic or eukaryotic. Classify the characteristics as being
unique to prokarytoic cells, common to both cell types, or unique to eukaryotic cells. Move each
description into the correct category.
Prokaryotic cells
1) relatively small, typically less than 10 micrometers in size.
2) contain DNA
3) nuclear membrane surrounds DNA
4) use ribosomes to synthesize proteins.
5) lack a true cytoskeleton - Answers 1) Relatively small, typically less than 10 micrometers in
size

A cell has a circular chromosome and histone proteins associated with its DNA, but lacks a
nuclear membrane.
Choose the domain of the cell with the best justification.
The cell belongs to the Eukaryota because it has a circular chromosome, which is present in
Eukaryota and Eubacteria but absent in Archaea
The cell belongs to Archaea because it has histone proteins, which are present in Archaea and
Eukaryota but absent in Eubacteria
The cells belongs to Eubacteria because it has hisone proteins, which are present in Eubacteria
and Eukaryota but absent in Archaea.
The cell belongs to Archaea because it has histone proteins, which are present in Archaea and
Eubacteria but absent in Eukaryota.
The cell belongs to Eubacteria because it lacks a nuclear membrane, which is present in
