All 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.
Which of the following statements regarding viral genomes is FALSE? Question options: viral genomes are always comprised of RNA viral genomes are smaller than the genomes of cellular life viral genomes can be either single-stranded or double-stranded viruses can have as few as three genes viral genomes do not encode ribosomal RNAs all these statements are TRUE The ______________ of a virus is a phospholipid bilayer with embedded proteins and glycoproteins Question options: capsid chromosome envelope nucleocapsid spike receptor
Select 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.
A viral envelope: is coded for in a viral genome is found within the capsid is not a true plasma membrane is part of some bacteriophages

Notice the white line indicating a reference for 100 nm. Which 3 viruses have a diameter (width) roughly equal to 100 nm?
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.
The classification of viruses are similar to the classification of organisms in the three domains of life. Discuss this statement critically.
