DNA – the very molecule that defines who we are. It is still fascinating that a molecule that is so small that is not visible to the naked eye determines not just our physical appearance but also our mental wellbeing. Over 60 years, the discovery of the double helix DNA had impacted various fields relating to Biology and Chemistry, contributing to the advancement of technology and subsequently mankind too. The discovery of DNA had opened up many opportunities in the field of genetics. By analysis a DNA of an individual, we are able to diagnose diseases that are hereditary at an early stage. Genetic diseases are diseases that arise from one or more abnormalities in a genotype (or genotypes) (Elston, 311). Genetic diseases such as sickle …show more content…
DNA – the very molecule that defines who we are. It is still fascinating that a molecule that is so small that is not visible to the naked eye determines not just our physical appearance but also our mental wellbeing. Over 60 years, the discovery of the double helix DNA had impacted various fields relating to Biology and Chemistry, contributing to the advancement of technology and subsequently mankind too. The discovery of DNA had opened up many opportunities in the field of genetics. By analysis a DNA of an individual, we are able to diagnose diseases that are hereditary at an early stage. Genetic diseases are diseases that arise from one or more abnormalities in a genotype (or genotypes) (Elston, 311). Genetic diseases such as sickle cell anemia and Down syndrome could not only just be detected, but predicted from the parents. Parents could be potential carriers, although not affected by the genetic disease, but still carry the gene of the disease, and could potentially pass it down to their children (Watson, 335). Through genetic testing, we could detect flaws in our genes that may potentially be passed down to our future generations and take the necessary precautions to minimize the impact of the genetic diseases, or optimally, removing the risk of having the disease completely. DNA plays the important role as a biological identification. According to Norah Rudin, through a series of experiments in the 1900s, it is found that DNA, similar to a fingerprint, are unique.
