(i) Transplantation of Organs: In case of transplantation of heart, lung, kidney, eye etc. from one body to another, it is necessary to know whether there is any adverse effect on donor or recipient. It is determined by DNA sequencing.
(ii) Prevention of side effects of drugs: Drugs cause various side effects in the human body. Genome sequencing can prevent drug side effects.
(iii) Preparation of medicine: In this method medicine can be prepared for specific diseases.
(iv) Gene therapy: Gene therapy can be given through this method. Gene therapy is a modern medical method.
(v) Detection of defective genes: Defective genes are harmful to the organism. In this method the sequenced gene is identified. After this, the sequenced gene is removed.
(vi) Cure of hereditary diseases: Through genome sequencing, causes of hereditary diseases like hemophilia, meiotic dystrophy, fragile X syndrome, neurofibromatosis-II etc. can be known and preventive measures can be taken.
(vii) Advance treatment: In this process the problems of various diseases can be known in advance and early treatment of diseases can be taken.
(viii) Cancer cure: Genome sequencing has successful application in research and treatment of cancer diseases. Genome sequencing is applied in cancer research such as colon cancer, breast cancer, somatic variation detection, transcriptome sequencing, virus tumor detection etc. Various topics of cancer research are being presented to researchers through bioinformatics.
(ix) Disease diagnosis: Genome sequencing is applied in some disease diagnosis. For example, Down’s syndrome.
(x) Treatment in short time: Accurate diagnosis is being made by applying genome sequencing. Extensive research is going on for proper treatment in less time and less cost.
(xi) Diagnosis of immune system: Reasons for susceptibility of people to disease and lack of immunity can be determined.
(xii) Alteration of DNA sequence: Direct application of various X-rays changes the DNA sequence.
(xiii) Control of Dengue: Genome sequencing technology has made control of the Aedes mosquito, the vector of dengue, possible. Researchers at the Oxitech company have created a breed of mosquitoes by altering genes. Their male mosquitoes cannot produce viable offspring. The larvae die soon after hatching. In this way, it has been possible to reduce 90% of mosquitoes in some cities in Brazil.
