- The genome of a virus consists of (a) DNA (b) RNA (c) prions (d) DNA and RNA (e) DNA or RNAAll of the following statements correctly describes the properties of Influenza A virus EXCEPT A-Viral transcription occurs in the nucleus B-Mature virion are released by budding C-Single stranded positive sense RNA virus D-Attaches to cell-surface sialic acidThe rabies virus is a negative strand single stranded RNA virus, simply referred to as (-) ssRNA. Describe how this virus produce mRNA and replicates its genome.
- Which is the usual order of a viral replication cycle when it is making new virions? O Host recognition > replication > entry > uncoating > release O Uncoating > host recognition > replication > entry > release O Prophase > metaphase > anaphase > telophase > cytokinesis Host recognition > entry > uncoating > replication > release MacBook Air DII DD F11 888 F8 F9 F7 F6 F5 F3 F4 & %24 % 7 8 LOWhich type of virus would not need a viral enzyme for transcription? retrovirus ds RNA ss (+) sense RNA s (-) sense RNAWhich of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. Rhinovirus
- Can Cytomegalovirus (CMV) release any toxicant? What I mean is if the virus perform any kind of chemical rection while inactive like when it is in the environment releasing toxins or when is active inside the host such as inside the human body?HPV viruses have a distinct capability to evade confrontation with the human immune system? What are the basic virus properties responsible for this capability? (Give at least 3)Match each of the following replication classes of viruses with the one description that best describes it. This virus class is composed of segmented and non-segmented helical viruses that carry an RdRp within the virion into the cell. Example: Rabies virus These viruses are non- enveloped, icosahedral, have segmented genomes, and carry their own RNA-dependent RNA polymerase. The viral genome is copied following assembly. Example: Reovirus This is the only class of RNA viruses whose genome is replicated by cellular enzymes and not an RNA-dependent RNA polymerase. Cellular DNA polymerases replicate this virus's non- integrated genome, although transcription is not the initial event that takes place in the process. Example: Parvoviruses In this class of viruses, transcription occurs before genome replication because viral proteins are involved in replicating the genome. Example: Adenovirus This class of viruses forms circular DNA and creates pre- genomic RNA using host RNA polymerases.…
