- 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.Which of the following statements about viruses is true?a) They contain DNAb) They contain RNAc) They contain proteind) They are susceptible to lipid solventsSelect all the following statements that are TRUE regarding viruses: □ All viruses are potentially dangerous to humans because any virus can infect any host. □ Viruses are fastidious pathogens that require complex growth media. □ Viruses are noncellular particles that take over the metabolism of a cell to generate more virus particles. □ Viruses are genomes made of RNA and DNA that lack many protein. □ Viruses can infect all other known life forms on earth, from Archaea to humans.
- The genome of which of the following types of animal virus can act directly as MRNA and be utilized by ribosomes without prior processing? O 1) retroviruses O 2) SSDNA viruses 3) -SSRNA viruses O 4) +SSRNA viruses 5) dsDNA virusesWhich of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. RhinovirusDiscuss the following statement: “Viruses exist in the twilight zone of life: outside cells they are simply dead assemblies of molecules; inside cells, however, they are alive.”
- Are viruses living or dead? Discuss this question by applying your knowledge of viruses and their life cycles.Why are viruses not considered living organisms?Viruses 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.
