chapter 1
Viruses are
infectious agents that infect exclusively multicellular organisms.
noncellular particles that take over the metabolism of a cell to generate more virus particles.
pathogens that replicate in complex growth media.
cellular particles that belong to the archaea domain.
microbes that consist of lipid membrane–enclosed genomes.
The analysis of DNA sequences reveals
the ancient convergence of prokaryotes and eukaryotes.
that prokaryotes and eukaryotes evolved from a common ancestral cell.
that bacteria share a common ancestor with archaea but not with eukarya.
that prokaryotes are cells with a nucleus.
that the genome of Haemophilus influenzae has about 2 billion base pairs.
Which of these groups are considered to be microbes, but NOT considered to be cells?
viruses
bacteria
archaea
protists
filamentous fungi
A microbe is commonly defined as a(n) ________ that requires a microscope to be seen.
virus
bacterium
single-cellular prokaryote
archaea
eye of a fruit fly
Which one of the following statements regarding microbial cells is FALSE?
Microbial cells acquire food, gain energy to build themselves, and respond to environmental change.
Most single-celled organisms require a microscope to render them visible, but some bacterial cells are large enough to be seen with the naked eye.
Microbes evolve at slow rates.
Many microbes form complex multicellular assemblages.
Viruses are not considered microbial cells.
Which of the following statements is FALSE?
A genome is the total genetic information contained in an organism’s chromosomal DNA.
If a microbe’s genome includes genes for nitrogenase, that microbe probably can fix nitrogen.
By comparing DNA sequences of different organisms, we can figure out how closely related they are.
Fred Sanger developed the first applicable DNA sequencing method.
