What is the sequence of the coding region of sars cov 2 virus's spike protein ?
Step by step
Solved in 3 steps with 2 images
- Syn5 is a virus that infects photosynthetic bacteria belonging to the genus Synechococcus. The Syn5 virion is icosahedral (660 Å in diameter) with a short tail and an appendage called a horn. The horn is located on a vertex directly opposite the tail. Syn5 follows the typical five steps observed for most viruses when they multiply, and progeny viruses are released when the host lyses. The assembly of Syn5 virions involves several proteins, including capsid proteins, scaffolding proteins, a portal protein, a terminase, tail proteins, and horn proteins. To better understand the assembly of Syn5 virions, scientists used a type of microscopy called Zernike phase contrast electron cryotomography. This type of microscopy improves the contrast typically seen for conventional cryotomography. In their studies, the scientists observed several different developing virus particles in infected cells. The particles were: (1) 660 Å icosahedron containing DNA and having a tail; (2) 660 Å icosahedron…Can you please pick the right answer in each parentheses? The spike protein of SARS-CoV-2 is a carbohydrate-modified protein that ["bind the RNA genome of the virus", "", "is on the surface of the viral particle", ""] and plays a role in both ["replication of the viral genome", "recognition of host cell"] and ["packaging of viral genome for export", "fusion of viral envelope with host cell plasma membrane"] . Importantly, earlier work on spike proteins from other corona viruses showed that this molecule ["remarkable resistance to immune response", "shows remarkable conformational changes"] and only one of these served as a good antigen for vaccine development. A critical discovery in advancing the development of our current vaccines was determining what changes in the amino acid sequence would ["block degradation of the spike protein", "stabilize the conformation of the protein found on the viral particle"]. This…How many protein subunits would be present in a complex icosahedral virus particle with a triangulation (T) number of 8?
- answer doesn't have to be long i just need an explanation, thank you! The whole world right now is concerned (or they should be) about the appearance of new variants of SARS-CoV-2. Among other things, these variant viruses have mutations that change the amino acid sequence of the spike protein on the virus surface. While this is concerning, I would like to propose that there is a limit to how far these mutations can change the spike protein. Why can't there be an endless number of new mutations of this viral protein? How would these amino acid changes affect how the virus works?HIV what is the genome for the virus? And, what Baltimore class does the virus belong to? does the virus have envelop? what are protein(s) on the virus that interact directly with the cellular receptors? how many cellular receptors are involved in the binding of the virus? what are they?1. "One structural form used in building virus particles is based on the icosahedron. Describe, either in words or in a diagram, the organization (number of capsomers, etc.) of the simplest virus particle of this form. 2. If a virus has a negative‐sense RNA genome, what enzymatic activity (if any) will be found as part of the virion, and what will be the first step in expression of the viral genome?"
- The complete coronavirus genome sequence from the first known patient infected with SARS-CoV-2 was published on January 10th 2020, just a short time after the patient had been hospitalized in China with respiratory symptoms. They did this so quickly using nanopore sequencing. Scientists compared the genome sequence from the new coronavirus (SARS-CoV-2) with the genome sequences from several other coronaviruses and they did identify a sequence unique to the SARS-CoV-2 strain. This unique sequence was in the N gene of the viral genome. What protein is made from the N gene of the virus?In the study of the SARS-CoV virus protein codes, it was discovered that eight potential open reading frames (ORFs) encode hypothetical SARS‐CoV‐specific proteins which lack obvious sequence similarity to known proteins. What possible function could these proteins have that would add to the infectious quality of the virus?describe the structure of a phospholipid and a phospholipid bilayer for corona virus
- Briefly describe how the Latency-associated transcripts (LATS) of herpes simplex viruses regulate viral latency within an infected cell.Describe the classes of viruses based on theirgenomic characteristics. For each class, describe how viralmRNA is made and how the viral genome is replicated.The dUTPase enzyme is used by the African swine fever virus to repair its own DNA, as the cells the virus infects in swine do not express the dUTPase protein. Which of the following is a reasonable explanation for the role of the dUTPase in the virus lifecycle? Explain your choice in 25 words or less. The dUTPase is necessary to remove dUTP from the viral genome, as uracil should not be present in DNA The dUTPase is necessary to remove dUTP from the viral genome, as uridine cannot correctly base pair with adenine-containing bases The dUTPase is necessary to remove dUTP from the viral genome, as uridine has the wrong sugar component for building DNA More than one of the above answers is correct None of the above answers is correct
