- True or false: RNA is conserved mechanism in eukaryotes. SDS is an uncharged detergent molecule. Transfection refers to the process of inserting nucleic acid into living prokaryotic cells. when choosing a secondary antibody you do not need to worry about the species in which the primary antibody was generated.Which of the following is a type of Immune Treatment gained from recombinant technology? Factor VIII Insulin Interleukins AntitrypsinIn an immunoassay, antibodies used to recognize and bind to antigens are called primary antibodies and are prepared by injecting animals with that antigen. Secondary antibodies recognize and bind to primary antibodies. Secondary antibodies are prepared by injecting antibodies from animals exposed to the antigen into another animal of the same species. only the 1st statement is true only the 2nd statement is true only the 3rd statement is true the 1st and 2nd statements are true the 2nd and 3rd statements are true the 1st and 3rd statements are true Write G if all the statements are true Write H if all statements are false
- You can choose one or more than one option Macrophages are found in basic IMMUNOLOGY Bone marrow Spleen Skin Blood liver The cytosol: basic CELL BIOLOGY is a static liquid inside the nucleus contains RNA supports the cell and determines its shape contains water as the major quantitative component chemically modifies proteins and other molecules Flu is a disease induced by the Influenza virus, we need to repeat every year the vaccination against the flu because: MICROBIO-VIROLOGY basic the vaccine against the flu contains inactivated viruses that stimulate immunity for 6 months. annual vaccination results in the production of IgA and not of other immunoglobulin the flu virus presents antigenic variation in its capsid proteins. the flu virus presents antigenic variation in its envelope proteins. the flu vaccine is expired after six monthsLabs that do a lot of Western blots often have hundreds of primary bodies but only two or three secondary antibodies. Why? I understand that secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody which directly binds to the target antigen. However, I don't undrstand why there are only two or three secondary antibodies available in the laboratory. Glad if the expert would advise.Which of the following statements would be a correct definition of an antigen? A B C D Non-self macromolecules that trigger an immune response. Non-self macromolecules found only on bacteria that trigger the formation of antibodies. Proteins that consist of two light and two heavy polypeptide chains. Self macromolecules embedded in B-lymphocytes cell membranes.
- Which of the following is an antigen that would only be recognized by a specific antibody? Group of answer choices The unique structure of a measles virus surface protein Peptidoglycan from bacterial cell walls The double-stranded RNA produced during infections by RNA viruses None of these would be recognized by an antibodyAntibody heavy and light chain polypeptides consist of repeated domains, each of which is ~110 amino acids and folds up into a compact three-dimensional structure known as an ‘immunoglobulin domain.’ These immunoglobulin domains are: Mixed and matched between different antibody heavy and light chains to produce variability Always identical to each other within a single antibody heavy chain or light chain polypeptide Always differ in amino acid sequence between different light chain polypeptides in both of the two light chain immunoglobulin domains Similar but not identical in amino acid sequence when comparing the domains in a single heavy chain polypeptide Identical in amino acid sequence for every domain when comparing different antibody heavy chain polypeptides to each otherWhich of the following best describes an attenuated whole-agent vaccine? Uses antigenic fragments of a microbe to stimulate immunity Uses living but weakened microbes to stimulate immunity Uses killed microbes to stimulate immunity Combination of antigens to enhance immune response Inactivated toxin (toxoid) that induces immunity against microbial toxin
- In this chapter, we described co-immunoprecipitation as a method for identifying binding partners to a protein of interest. A simpler variation of this method can also be used to isolate proteins of low abundance in a complex mixture. Arrange the steps in sequential order to use this technique for this purpose. First step Last step Answer Bank The protein mixture is centrifuged, the supernatant is removed, and the pellet is washed. The antibody binds to the protein of interest. The antibody-protein complexes become insoluble. An antibody against the protein of interest is added to the mixture. Protein A beads are added to the mixture.Herd immunity means that the entire population (not just those who are vaccinated) are protected from a disease. What is one way that herd immunity protects an unvaccinated person (such as an infant who is too young to be vaccinated or a person who is immunocompromised)?True or false Edward Jenner first proposed protective vaccine against plague in the 18th century. Herd immunity protects infection of vaccinated population but not in the unvaccinated population. Long term health problems after COVID-19 infection is called Long COVID. Cerebellum of the brain co-ordinates muscle movements. Neuron is a special type of cells in the brain and nervous system.
