One of the great promises of genomic research is personalised medicine: tailoring disease treatments to an individual’s genetic makeup. Many drugs that are currently available are “one size fits all,” but they don't work the same way for everyone. It can be difficult to predict who will benefit from a medication, who will not respond at all, and who will experience negative side effects (called adverse drug reactions). Adverse drug reactions are a significant cause of hospitalizations and deaths in the United States. With the knowledge gained from the Human Genome Project, researchers are learning how inherited differences in genes affect the body’s response to medications. So, statement (3) is correct. DNA sequencing is a laboratory technique used to determine the exact sequence of bases (A, C, G, and T) in a DNA molecule. The DNA base sequence carries the information a cell needs to assemble protein and RNA molecules. DNA sequence information is important to scientists investigating the functions of genes.
The technology of DNA sequencing was made faster and less expensive as a part of the Human Genome Project. So, statement (1) is correct. Any disturbance in the structure or function of any organ or part of the body may be caused due to the attack of pathogens (virus, bacteria), lack of nutritious diet/balanced diet and lack of public health services. So there are many reasons due to which a disease occurs. Diseases can be spread across a wide spectrum, with predominantly genetic diseases at one extreme of the spectrum and diseases of largely environmental origin at the other. In the genetic part of the spectrum are diseases such as Turner’s syndrome; in the environmental part are infectious diseases and chemical poisoning. Hence we can use genome sequencing to determine the causes of only some diseases and not all. So, statement (2) is not correct. Therefore, the correct answer is b.
