Question

What are genes and why are medical researchers always trying to find out more about them? Genes are part of the centre (that is, the nucleus) of every living cell: in the form of DNA (deoxyribonucidic acid), this biological genetic material determines the characteristics (features) of every living thing-every plant a l and human being on Earth Medical geneticists are scientists that study DNA and genes for many puposes (1) to learn how living things such as parasites, viruses, and bacteria cause illness, (2) to find the gene or combination of genes that cause certain discases to pass from parents to their children, (3) to prevent correct (repair) birth defects, (4) to change gene structure to improve health and increase the length of human life (longevity), and (5) to change the biological characteristics of animals and rates in ways that are beneficial to society. Another use of genetic technology that some scientists support is changing the genes of the food farmers grow Genetic engineers claim that these differences in DNA structure will increase food production, prevent damage from insects, and improve world health, in contrast, others oppose the use of genetic engineering not only in plants but also n animals and humans. what is the main idea of this paragraph? ​
