Describe the importance of modern achievements of genetics for human health

It is thanks to genetics that such therapeutic methods are being developed thanks to which diseases previously incurable can be treated. Thanks to the modern achievements of genetics, there are now DNA and RNA samples, thanks to which cancer can be detected in the early stages. Also learned to get enzymes, antibiotics, hormones, amino acids. For example, for those with diabetes, insulin was obtained by genetic methods.
On the one hand, modern advances in genetics provide new opportunities for diagnosis and treatment of humans. On the other hand, the achievements of genetics adversely affect human health through the use of food, expressed in the widespread distribution of genetically modified foods. When these foods are eaten, immunity may weaken, general condition, antibiotic resistance may worsen, cancer may appear, the gastrointestinal tract (GIT) first of all suffers.
