With the development of science and technology, the application of isotope labeling methods is becoming mature. For example, in molecular biology, studies on photosynthesis using isotopes such as C and O can elucidate in detail how chlorophyll utilizes carbon dioxide and water, what is an intermediate for forming macromolecules such as sugars from these simple molecules, and conditions affecting biosynthesis reactions in each step. By studying the interrelation of the C, H, P, and other alleles to nucleic acids and proteins, not only can the complex process of nucleic acid and protein production in vivo be understood, but also the possibility of how biogenesis is realized, and even the possibility of artificially modifying genetic characteristics is discussed, and thus, new subjects such as molecular genetics and genetic engineering are generated based on the above. In addition, in the fields of agriculture and animal husbandry, the radioactive isotope tracer technology is also widely applied to agricultural science research, and great economic benefits are generated. Biological effects such as insecticides, herbicides on insects and weeds; the effects of plant growth stimulants on crop metabolism and function; the influence of hormones, vitamins, trace elements, feed and medicaments on the growth and development of livestock; and the life cycle, migration law, mating and foraging habits of the large and small animals and the like found by labeling insects, parasites, fish, animals and the like with isotopes are all technical achievements generated by research on tracing technologies.
