What is the membrane that surrounds a capsid? What is a capsid?Antigenic Drift:Antigenic drift is the term used for the genetic sequence point changes of various infectious viral pathogens, such as Influenza A and Influenza B, that results in the mutation of its protein products, speci...
What is the purpose of phage typing? Lambda Phage: Lambda phage refers to a virus that is known for infecting bacteria called E.coli. The head of this virus is known as capsid and constitutes the genome of the virus. The binding between this virus and E.coli occurs with the help of J...
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...
it is known as a virion. According to "Medical Microbiology" (University of Texas Medical Branch at Galveston, 1996), simple virions contain an inner nucleic acid core surrounded by an outer casing of proteins known as the capsid. Capsids protect viral nucleic acids from being chewed up and...
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...
Most viruses have icosahedral or helical capsid structure, although a few have complex virion architecture. An icosahedron is a geometric shape with 20 sides, each composed of an equilateral triangle, and icosahedral viruses increase the number of structural units in each face to expand capsid size...
* Capsomers are the building blocks/units of the capsid in viruses.* Some of the viruses appear spherical because they are enclosed within an envelope.Viral GenomeEssentially, a virus may contain DNA or RNA but never both. Therefore, a given virus may be classified based on the type of ...
(flu, HIV) and protein. Some viruses also have lipids. A virus is basically a protein container (capsid) with nucleic acid inside. The only purpose of viruses is to reproduce. A virus is basically a protein container (capsid) with nucleic acid inside. The only purpose of viruses is to ...
Which type of T cells is most effective against viruses? What component of a virus is lacking in a cell? What organisms cause infectious disease? What is the difference in how a virus and bacteria replicate and affect cells of the body?
Capsid What are chromosomes made of, from DNA, RNA, and protein, or just DNA and RNA? What do you call the protein shell that encloses a viral genome? What is a change in the nucleotide sequence of an organism's DNA or in the DNA or RNA of a virus called? What are the ...
