What is the capsid of a virus, and what is its function? How are the two types of capsids constructed? Which of the following does not get infected by viruses? a) Plants b) Animals c) Bacteria d) All of these can be infected by viruses. ...
What is the capsid of a virus, and what is its function? How are the two types of capsids constructed? Bacteriophages differ from plant or animal viruses in that: \\ A. they lack an envelope B. they are more prone to kill their host rapidly C. they have RNA instead of DNA and thu...
any consequence of overuse / antibiotic no longereffective ;(d)X-rays caused mutations ;change in DNA ;ref to, gene / allele ;mutation causes antibiotic resistance ;(e)assume answer is about bacteria unless told otherwise, accept oraAVP for viruses e.g. capsidbacteria have cells ;cell wall ...
The ratio between genome equivalents (GE) and infectious particles has been reported to increase with time, and is strongly dependent uponwater and climatic conditions and virus type. Damage to the virus capsid may result in the loss of its capacity to protect the genome and its ability to rep...
Studies of viral replication indicate that most viruses self-assemble as a result of interactions between the viral proteins to form a viral capsid that interacts with the nucleic acid to form the whole. The viral replication cycle and synthesis is presented in this chapter. Viral classification ...
Viruses consist of a stand of genetic information ( DNA or RNA ) inside a protein shell called a capsid. Some viruses also have a membrane layer around them. Viruses use cellular components of the host cell to reproduce. New viruses are then released from the host cell which then search fo...
What does the envelope of the virus fuse with in order to release the viral capsid into the host cell? Describe how an animal virus infects a host cell, in general. What is the scientific name of a disease-causing organism? A. Patho...
A virus refers to a pathogenic entity capable of infecting host cells, while a virion is the complete, infective form of a virus outside a host cell, comprising RNA or DNA enclosed in a protein coat.
* The protein helix structure serves to protect the nucleic acid.* The nucleocapsid is about 1,000nm in length and about 17nm in diameter.Icosahedral SymmetrySome of the viruses with an icosahedral capsid include human rhinovirus, rice yellow mottle virus, cricket paralysis virus, and porcine ...
The innate and the adaptive immune system are able to recognize viral pathogens when the antigens (receptor of the virus) are identical to the previous infection. The recognition is accurate and highly specific, which mounts a well-orchestrated response. The production of memory cells, wh...
