about SARS-CoV-2 from literature and discuss how each biomacromolecule class (proteins, enzymes, carbohydrates, lipids and
Step by step
Solved in 2 steps
- A comparison of plaque-forming units and TCID50 units as measures of virus infectivityOf all the characteristics of viruses (types of capsids, viral nucleic acid, and viralgenome), explain how these characteristics affects the potency and virulence ofcertain virus.SARS-COV-2 is mainly transmitted through respiratory droplets when an infected person sneezes, coughs, or talks. how might this relate to the size and/or structure of viruses?
- about SARS-CoV-2 discuss how each biomacromolecule class (proteins, enzymes, carbohydrates, lipids and nucleic acids) is important in viral life cycle and infectivity.The (spike or nucleocapsid) of sars-cov2 binds to the (envelope or ACE2) on epithelial cells in which allows the (RNA or DNA) of the viruses to replicate.There are several corana virus in database, why is the SARS-CoV- 2 so dangerous
- Indicate whether the following sentences is either True or False and CORRECT the wrong sentences : Simian Virus 40 (SV40) is an example of is a circular ssDNA belong to Polyomavirus, was first isolated from primary cell cultures derived from rhesus monkey kidneys, and activates p53. SARS-COV-2 is an enveloped, icosahedral virus that is surrounded by a lipid bilayer and causes COVID-19 pandemic.virion. Describe how the Baltimore classification system classifies viruses.a. Consult table, right-hand column, to determine which viral diseasesyou have had and which ones you have been vaccinated against.b. Which viruses would more likely be possible oncoviruses? Why?
- Reverse transcriptase is an error prone DNA polymerase. Describe the role of reverse transcriptase in viral propagation and how having an error-prone enzyme might make it challenging to have a vaccineThere are several coronavirus in the database, why is the SARS-CoV-2 so dangerousMechanisms and enzymes involved in SARS coronavirus genome expression
