What does virus specificity mean?
Virus specificity refers to the ability of a virus to infect specific host cells or organisms due to interactions between viral and host cell surface molecules. Each virus has a specific range of hosts that it can infect based on these molecular interactions, which determine its infectivity and pathogenicity. This specificity is what underlies the diverse range of diseases caused by different viruses.
What are the different types of enzyme specificity with examples?
Enzymes exhibit different types of specificity, including substrate specificity (acting on a specific substrate), stereospecificity (acting on a specific stereoisomer), and regiospecificity (acting at a specific region of a substrate). For example, trypsin exhibits substrate specificity by cleaving peptide bonds after lysine or arginine residues, while lactase exhibits substrate specificity by hydrolyzing lactose.
What is most important for attachment of a virus to a host cell?
While we are constantly referring to bi-lateral specificity, as in the functions of Dna, here is a case where a virus offers out it's 'hand': it seems likely that it expects to reach for, find and attach to some outstretched Cell Membrane Component.
What would be unlikely to contribute to the substrate specificity of an enzyme?
The size of the enzyme's active site would not contribute significantly to substrate specificity. Substrate specificity is typically determined by the shape, charge, and chemical properties of the active site that can properly bind to the substrate.
What causes enzyme specificity?
Enzyme specificity is mainly determined by the active site structure and the interactions between the enzyme and its substrate. The shape, charge, and chemical properties of the active site are crucial in determining which substrates can bind to the enzyme and undergo a catalyzed reaction. Additionally, enzymes undergo conformational changes upon substrate binding to further enhance specificity.
How does Viral specificity work?
Viral specificity refers to the ability of a virus to infect certain host cells or species while bypassing others. This specificity is determined by the interaction between viral surface proteins and specific receptors on the host cell membranes. The compatibility between these proteins and receptors dictates whether the virus can attach, enter, and replicate within the host. Additionally, factors such as host immune responses and cellular environments can further influence viral specificity.

How do you quantify the virus in a given sample?
To quantify a virus in a sample, techniques such as quantitative PCR (qPCR) can be employed, which measures the amount of viral genetic material present. Another common method is plaque assay, where viral particles are diluted and added to a cell culture, and the number of plaques formed indicates viral concentration. Additionally, techniques like ELISA can measure viral proteins, providing another means of quantification. Each method has its own sensitivity and specificity, depending on the virus and sample type.

What viral characteristics are shared with other organisms?
Viral characteristics shared with other organisms include the presence of genetic material (either DNA or RNA), the ability to evolve through mutation, and the capacity to reproduce and spread within a host organism. Additionally, like other organisms, viruses exhibit some level of specificity in terms of host range and cellular tropism.

specificity
Does the shape of an enzyme protein determine specificity?
Shape of an enzyme specifically shape of its active site determines enzyme specificity .
