Biotechnology Engineering Interview Questions and Answers
Question - 51 : - Is body itself a bio technology?
Answer - 51 : -
Yes, it has to be articulated as a technology. But not by nature, once its articulated or framed in such a way, then definitely it’s a technology. Anything which is re-framed from a naturally occurring bio logical process is called bio technology.
Question - 52 : - What do you mean by bio-media?
Answer - 52 : -
It’s a concept which means to describe the informatic reframing or biological components and its methods and processes. Its all about the process of identifying biologically and looking through the lens of informatic.
Question - 53 : - How is this bio technology useful in our day to day life?
Answer - 53 : -
Bio technology is used to help in solving the problem faced in our daily products. Yogurt, wine, cheese, and antibiotics these are all not new for human beings. This method of bio technologypromises a better way of retaining the essence and preventing disease.
Question - 54 : - What are primary mediators?
Answer - 54 : -
Primary mediators are those, which are produced before degranulation. These primary mediators are stored in granules. Some of the primary mediators are histamine, heparin, proteases etc.
Question - 55 : - Explain in brief about histamine
Answer - 55 : -
It is formed by the decarboxylation of amino acid histidine. It accounts for 10% of granule weight. This histamine binds to specific receptors on various target cells.
Question - 56 : - Explain in brief about leukotrienes and prostaglandins
Answer - 56 : -
Leukotrienes and prostaglandins are formed only when the mast cell undergo degranulation and enzymatic break down of phospholipids in the plasma membrane.
The effects produced by them are more pronounced and long lasting than histamine. Leukotrienes mediate mucous production and bronchoconstriction. Prostaglandin D2 causes bronchoconstriction.
Question - 57 : - Explain in brief about cytokines
Answer - 57 : -
Cytokines activate inflammatory cells such as neutrophils and eosnophils.IL-5 is important in activation of eosnophils, IL-4 increases IgE production by B-cells. IL-4, Il-5, IL-6, TNF-a has been secreted by human mast cells.
Question - 58 : - What is type II hypersensitivity?
Answer - 58 : -
It is IgG mediated cytotoxic hypersensitivity. Typical manifestations include erythroblastosis fetalis, hemolytic anemia, blood transfusion reactions etc.
Question - 59 : - Give some symptoms of serum sickness.
Answer - 59 : -
Symptoms include fever, weakness, rashes, with erythema and edema. Serum sickness depends on the immune complexes formed and the size of the complexes.
Question - 60 : - Name some Infectious diseases.
Answer - 60 : -
Some of the Infectious diseases are Malaria, meningitis, trypanosomiasis, hepatitis etc…
