Step by step
Solved in 2 steps
- Which is not a virus encoded protein that participates in viral DNA synthesis? Group of answer choices Rb protein Origin binding proteins Exonucleases DNA polymerase and accessory proteinsChoose the correct the correct answer Viral particicles contain both nucleic acid and protein and can replicate inside of a host cell. Technically, this constitutes a "self -replicating molecular assemblage" which is also one way to define life. Therefore, one can conclude that a. Viruses are not living because they don't breathe oxygen b.Viruses are living c.Viruses are not living because they cannot think d. Viruses are not living because this formationis a simple repetitive process without the ability to respond to the environmentClassification of viruses is based on all of the following excepta) type of nucleic acid. b) shape of virus.c) size of virus. d) host infected.e) strandedness of nucleic acid.
- Viruses with reverse transcriptase enzyme can make a DNA copy out of its RNA genome. What implications can this capability do in health hazards?Which statement is true? A virion contains DNA and RNA. Viruses are acellular. Viruses replicate outside of the cell. Most viruses are easily visualized with a light microscope.Throughout history there are many different types of virus that have caused impacts both small and large. Is there a possibility a virus could be considered a "good virus"? Please provide an argument for both yes and no with the use of a proper example, facts and conceptual information.
- The Ebola virus is an enveloped, helical ssRNA virus that replicates quickly. Given this information, which one of the following is a reason why Ebola infection is difficult to fight (both by our bodies and by treatments)? Question 6 options: Because it has many genes and thus replication is slow. Because it doesn't have a membrane. Because viral RNA polymerases make a lot of mistakes. Because it can integrate into the host cell DNA. Previous PageNext PageWhat are two things that are true about all known viruses? Hint: one relates to the virus itself, the other relates to the ability of the virus to reproduce (replicate).Viral chromosomes exist in a variety of conformations and can be made up of ________.
