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.

Discuss 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.”

- please give answer asaparrow_forwardResearchers 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?

- Viruses with negative sense RNA genomes typically, make proteins by: (Ignore retroviruses, and the unusual characteristics of coronaviruses) Translation of short RNA transcripts generated by RDRP Generating a DNA copy, which is then transcribed by host RNA polymerase. Translation of the viral genome by host ribosomes. Production of a polyprotein, which must be cleaved into smaller proteins. Generating a negative sense genome copy, which is then translated by host ribosomes.arrow_forwardWhich biological system contains a protein nucleocapsid surrounding 2 antiparallel polynucleotide strands (held together by hydrogen bonds), with deoxyribose sugars, but no ribose sugars? a single-stranded RNA viroid (like avocado sun blotch viroid) a double-stranded RNA virus (like the reovirus family) a single-stranded DNA virus (like fX174 virus of E. coli) a double-stranded DNA virus (like the smallpox virus) a single-stranded RNA virus (like tobacco mosaic virus)arrow_forwardAll viral genomes contain nucleic acid, either DNA or RNA but not both. Viral replication is the formation of biological viruses during the infection process in the target host cell. Viruses must first enter the host cell before viral replication can occur. After gaining entry into a cell, the viral genome has to be first replicated using either the host DNA polymerase or RNA polymerase You are studying two viruses: Virus A is an enveloped RNA virus Virus B is non-enveloped DNA virus Which of the above viruses is likely to have the lowest mutation rate in the host cell? O Virus A because it uses the host RNA polymerase which has lower error rate than DNA polymerase. O Virus A because it uses the host DNA polymerase which has lower error rate than RNA polymerase. O Virus B because it uses the host DNA polymerase which has lower error rate than RNA polymerase. O Virus B because it uses the host RNA polymerase which has lower error rate than DNA polymerase.arrow_forward
