- Why are virus genomes small?arrow_forwardWhen a virus infects eukaryotic cells, one fate of the cell is lysis. List and briefly describe two other potential fates.arrow_forwardViruses are made up of the same biomolecules as cellular organisms (DNA, RNA, proteins, lipids, etc.). They infect cells and replicate themselves using resources from the host cells. Scientists discovered a previously unknown strain of virus in the tropical Pacific Ocean and it can infect higher-order eukaryotes. Initial analysis revealed that the virus is mainly composed of nucleic acids, proteins, and lipids. Chemical analysis after complete hydrolysis revealed the following building blocks (by weight): Chemical components Nucleosides Amino acids Lipids, phosphates, and carbohydrates Percentage by weight 20 30 50 Analysis of percentages of nucleosides yielded the following results (by molar ratio): Nucleosides A G T C U Percentage by mole 19 29 19 29 4 Researchers determined that the lipids found in the virus form a bilayer membrane surrounding the virus, and are obtained from the membrane of the host cell during virus maturation and exit from host cell.

- What enzyme is responsible for the production of viral DNA from a retrovirus?arrow_forwardViruses are made up of the same biomolecules as cellular organisms (DNA, RNA, proteins, lipids, etc.), which are synthesized through enzymatic dehydration reactions from building blocks and disassembled by enzymatic hydrolysis. They infect cells and replicate themselves using resources from the host cells. Scientists discovered a previously unknown strain of virus in the tropical Pacific Ocean and it can infect higher-order eukaryotes. Initial analysis revealed that the virus is mainly composed of nucleic acids, proteins, and lipids.

- As a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.arrow_forwardHow does an animal virus replication cycle differ from that of a bacteriophage?arrow_forwardViruses are host-specific, meaning they can only infect specific types of host organisms. For examble, the adenovirus is responsible for the common cold in humans but your dog can't catch a cold from you. Why is this? The proteins on the virus surface can only bind with proteins on the correct host surface. It is an enveloped or non-enveloped virus. The enzymes carried by the virus are compatible with the host. The genome of the virus is made of DNA or RNA.arrow_forward
- After a positive strand RNA virus ( Such as Coronaviruses) enters the host cell, the RNA is translated by ribosomes to create proteins associated with the virus (Such as, for example, the surface antigens like E and Spike proteins). How then, would the genetic material itself be replicated to be incorporated into the new viruses?.arrow_forwardA virus does not contain ribosomes. How does it manage to ensure the synthesis of its proteins?arrow_forwardWhat are specific structures present in viruses but not cells?arrow_forward
