Summarize the relationships between the following types of organisms with respect to genome size: viruses, bacteria,
archaea, and eukaryotes.
What will be an ideal response?
ANSWER: Viruses have the smallest genomes of these four types of organisms. Bacterial and archaeal
genomes are similar in size to each other. Eukaryotes have the largest genome sizes of these
four groups. There is overlap among the groups, however, in that viral genome sizes overlap
with genomes from archaea/bacteria, and eukaryote genome sizes overlap with genomes from
archaea/bacteria.
