Science assignment
Heredity or inheritance are features that are transmitted genetically from parents to their children or offspring. DNA or genetics was first discovered in 1869 by Friedrich Miescher after finding a phosphorus matter inside of the nuclei which was named deoxyribonucleic acid. DNA is a self-replicating material and is present in all living organisms. It is the carrier of genetic information. This report will be explore the ideas of scientists that help form our current understanding of DNA as well as comparing their ideas to others. Throughout history many scientist have made discoveries that contributed to our current understanding today. In this report we will be comparing the findings and technology of Walter Sutton, Thomas Hunt Morgan, Oswald Avery and Alfred Hershey. …show more content…
Doctors can diagnose patients and detect what they are susceptible to according to the patient’s complement of genes. In Agriculture, for example, DAF Queensland has been proactive in planting Barley varieties that carry adult plant resistance genes Rph 20 and Rph 23 to prevent barley leaf rust damaging their crops. Scientists in Rotterdam have found a gene that affects how old people look. Companies can now work on a product to prevent the ageing process. The discovery of the CD33 Alzheimer’s disease gene has companies working on a drug to prevent nerve cell death. Forensic science has benefitted hugely because of DNA testing. Inheriting a genetic set of conditions such as cancer, heart disease, depression, etc., cannot be changed. However, we can choose to prevent it from happening by lifestyle changes in the workplace, at home, in school by taking the stress out of tasks, such as homework and difficult assignments. Epigenetics, above and beyond genes, is the 21st century
