Erythroblastosis Fetalis: Hemolytic disease of the newborn

  Mismatching of the mother's blood group with her fetus can cause brain damage to the fetus Erythroblastosis Fetalis: Hemolytic disease of the newborn H ypersensitivity ! when intolerance undesirable reaction produced by the normal immune system is known as hypersensitivity. Depending upon the immunologic aspects hypersensitivity reaction can be categorized into 4types .ie. Hypersensitivity type I, II, III, and IV. When our body shows hypersensitivity then it may cause various types of damages. Anaphylaxis, allergic rhinoconjunctivitis, etc are examples of hypersensitivity.  Transfusion reaction of mismatching blood group Our blood group containing RBCs .ie. Red Blood Cells are encoded by different genes. Each of which has several alternative alleles. An individual possessing one allelic form of a blood group an antigen can recognize other allelic forms on transfused blood as foreign and mount an antibody response.  Here is an example of a transfusion reaction. If in a case indivi

DNA Profiling

DNA Profiling: enhancing the control of Crime through emerging technologies  How crime can be controlled by specific Biotechnology Applications of DNA Fingerprinting? D NA. i.e.Deoxyribose Nucleic Acid acts as genetic material. The unique property of the DNA due to its chemical properties. The chemical structure of everyone's DNA is the same but the only difference between person DNA is the order of the base pairs. Hence the result is every person could be identified solely by its sequence of their base pairs.  DNA profiling is a technique used to distinguish between individuals of the same species using only samples of their DNA. This is a method used to identify an individual from a sample of DNA with the help unique pattern that is present in their DNA. The original DNA fingerprinting technique was developed by Alec Jeffreys in 1985 . DNA Profiling knew as DNA testing, DNA typing, genetic fingerprinting, and DNA fingerprinting .DNA fingerprint is an analysis of the nitrogenous
