Textbook Question
Chapter 5, Problem 6Q
Viruses use the host cell cytoplasmic space as their “factories” and their enzymes and other macromolecules as their “tools.” Does that make them more sophisticated or less sophisticated than cells? Justify your answer.

Which of the following statements accurately distinguishes
between viruses, prokaryotic cells, and eukaryotic cells?
Viruses are not cellular and require a host to replicate, prokaryotic cells
lack a nucleus, and eukaryotic cells contain a nucleus and other
membrane-bound organelles
Viruses, prokaryotic cells, and eukaryotic cells all contain a nucleus
Viruses and prokaryotic cells are always unicellular, while eukaryotic
cells are always multicellular
Viruses do not contain organelles, while prokaryotic and eukaryotic cells
do
Researchers have recently discovered giant viruses that are 1 μm in length, the same size as some bacterial cells. The genomes of these viruses contain over 2 million base pairs of DNA, which is more DNA than is found in many bacterial genomes, and their genomes contain hundreds—in some cases, thousands—of genes. Given these observations and what you know about viruses, should viruses be considered living or nonliving? Give arguments for and against considering viruses as living organisms.
Some retroviruses that have a wide host range have been developed for use in treatment of diseases or syndromes. These viruses do not result in a productive infection because they lack critical genes for viral
replication, but they do carry DNA sequences that allow them to be packaged into infectious particles. Once in the host cell the viral DNA is released and integrates into the cell's genome. The advantage to this
strategy is that the delivery of the DNA is very efficient. What is one possible problem of using a virus that can integrate into the human nuclear genome?
Multiple Choice
The virus carries genes that will interfere with host cell activities.
The viral DNA sequences could still cause a disease.
Since the viral DNA sequences no longer contain essential genes for viral replication the host cell may not be able to replicate either.
The integration could disrupt an essential gene or genes.

- How is the entry (penetration) of an animal virus into its host cell similar or different to the entry of a bacteriophage into its host cell? The entire viral particle (capsid and genome) can penetrate an animal cell, while only the viral genome can penetrate a bacterial cell. There is no difference; the entire viral particle (capsid and genome) penetrates both cell types. There is no difference; only the viral genome penetrates both cell types.

- The cell is the basic unit of all living things, and viruses which are generally not considered living but have the ability to infect cells. Describe how the structure of a virus compares to the structure of a cell. You should explain (not list) at least two similarities and two differences between features of cells and viruses including a brief explanation of the function of those structures. Explain why viruses need cells.arrow_forwardWhich of the following is one way a virus can enter the host cell? Depending on the type of virus, each of the choices is a potential entry mechanisms. A virus can gain entry by fusing its membrane with the host cell's membe to transfer its genome into the host cell. A virus can gain entry by injecting its genome into the host cell. A virus can gain entry by fusing with the host cell's membrane so that the entire virus enters the host cell.arrow_forwardViruses that infect bacterial cells do not infect human cells, and viruses that infect human cells do not infect bacterial cells. Explain why this should be the case.arrow_forward
