Concept explainers

Virus

Viruses are infectious microscopic agents that can only reproduce in live cells of animals, plants, or microbes and are smaller than bacteria. Vertebrates, invertebrates, plants, protists, and fungi are among their many hosts. Viruses are unable to multiply on their own due to the lack of necessary cellular machinery, but they can guide the cell machinery of a host to make additional viruses by infection. The virus enters and attaches to a particular host cell, injects its genetic material, and reproduces by using the host’s genetic material. Viruses cause infection by taking entry into the host cell and using the host cell’s enzymes and raw materials to multiply.

Why do the two types of viruses differ if each has plus configuration single stranded RNA as its genome?
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.
Unlike some positive (+) strand RNA viruses, what must all negative (-) strand RNA viruses package within virions in order to o make mRNA upon infection of new host cells?
A virus does not contain ribosomes. How does it manage to ensure the synthesis of its proteins?
Some viral genomes, composed of single-stranded RNA, act as mRNA. What advantage might these viruses have over other kinds of viruses?
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?.
Rhinovirus and the flaviviruses have a _________ RNA genome, which ___________________ bind in order for translation to occur. As with most viruses with such genomes, they produce a ________________ (type of peptide), which is cleaved in order to produce the individual viral proteins
In some viruses, capsomeres function as enzymes as well as structural supports. Of what advantage is this to the virus?
Viruses 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. 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 Which of the following events mostly involves hydrolysis reaction after the virus infects…
Assume you isolate a single stranded (+) RNA virus. When you examine the proteins in the virus, you find that it does NOT contain replicase enzymes within its capsid. Which of the following is true? This virus must have a gene that encodes replicase. This virus will not be able to enter a host cell. Its genome cannot be translated (the process of translation) by the host cell ribosomes. A DNA copy of the viral genome has to be made before viral genes are expressed. This virus must lack surface antigens.
briefly explain the situation below. Larger viruses usually have a double-stranded genome, whereas small viruses typically have a single-stranded genome. What reasonable explanation can you offer for this observation?
Why is it essential that negative-strand viruses carry an enzymein their virions?
