All HPV are non-enveloped double stranded DNA viruses. Their genomes are circular and approximately 8 kilobase pairs in size. Most encode eight major proteins, 6 located in the “early” region and 2 in the “late” region. The “early” proteins are regulatory in function.... Can you please elaborate about the HPV genome in more detail that what I posted above? Thanks.

Because viruses lack some of the traits seen in all living things, many scientists do not believe viruses to be genuinely "alive." Using a few characteristics of live organisms as examples, explain why viruses may not be truly "alive."
Which of the following statements accurately distinguishes between viruses, prokaryotic cells, and eukaryotic cells? Viruses are not cellular and require a host to replicate, prokaryotic cells lack a nucleus, and eukaryotic cells contain a nucleus and other membrane-bound organelles Viruses, prokaryotic cells, and eukaryotic cells all contain a nucleus Viruses and prokaryotic cells are always unicellular, while eukaryotic cells are always multicellular Viruses do not contain organelles, while prokaryotic and eukaryotic cells do
Part B - Viral Classification: The Baltimore Scheme The Baltimore classification scheme is based on the relationship between the virus' genome and its mRNA. For the following choices, indicate which viruses would fall into each classification: 1) require reverse transcriptase to copy the information in their own genome to DNA; 2) can replicate and be transcribed in the same manner as the cell's own genetic material; and 3) a replicative form of DNA must be produced and is used for both replication and transcription. Drag and drop choices to the bins they describe. double-stranded DNA viruses Requires reverse transcriptase double-stranded RNA viruses retroviruses double-stranded DNA viruses that have an RNA intermediate Functions similarly to cell's own genetic material plus-strand RNA viruses minus-strand RNA viruses Reset Help plus-strand DNA viruses Uses a replicative form of DNA
Humans often use many proteins to accomplish a single function while many viruses accomplish multiple functions with a single peptide. What is an example of a virus and its single viral protein that accomplishes multiple functions? Why is it that this virus must be so efficient (doing so much with only one protein)? Why is this not the case with humans and pathogens that are relatives of humans?
