17. explain the strategy used by a plus-sense RNA virus, minus-sense RNA virus, DNA virus and retrovirus to get each of their genomes copied during replication [Hint: see the table if you cannot remember] 18. explain the strategy used by each of the following viruses to get host cells to make their proteins for them: double-stranded DNA, plus-sense RNA, minus-sense RNA, retroviruses [Hint: see the table if you cannot remember]

1. In retroviral replication (such as HIV) reverse transcriptase is used to convert viral ds RNA into viral ds DNA viral ss RNA viral mRNA viral ss DNA 2. Many viruses undergo an uncoating process prior to replication. Which statement depicts the uncoating process? the virus destroys the host nuclear membrane allowing it access to DNA the virus sheds its protein coat the virus shed its envelope when entering the cell via the cell membrane the virus sheds its...

COVID 19 is a positive sense single stranded RNA virus. Which of the following is the case, given this information? It integrates its RNA into a host cell this group of viruses is not generally known to infect humans It requires viral reverse transcriptase to convert its genome into a positive sense RNA strand it has a double stranded genome the genome does not need to be transcribed in order for viral proteins to be produced

8) The Replication of Coronavirus is depicted in Figure 1 (See below). As you can see in Comment 2, it is not clear whether the virus gets into the host cell by FUSION or RECEPTOR-MEDIATED ENDOCYTOSIS. Please define & describe the entry of a virus by FUSION and by RECEPTOR-MEDIATED ENDOCYTOSIS. How could a Coronavirus enter a cell? Which mechanism do YOU THINK is most likely correct? Why?

1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...

1.In early March, it was reported that two main strains of SARS-CoV-2 had been identified, termed S and L, with the S type being the less virulent ancestral form representing about 30% of prevalence and the more virulent L type having descended from the S type and representing about 70% of prevalence. However, the prevalence of the more virulent L type seems to have decreased after early January, and it is thought that this resulted from human intervention against this...
