Marine biotechnology is the sub-discipline of the field of biotechnology which deals with the application of cell biology, molecular biology and biotechnology. It is linked with the exploration of the ocean at the surface and the seafloor. It is connected to the study of marine animals and plants and also the non-living components of the marine environment such as sand, water and rocks. So as to derive chemical compounds from them to produce cosmetic products, drugs and medicine. It also deals with the improvement in the aquaculture and seafood production, preparation of biofuels from the marine animals and plants.
Among the options given Medicines based on chemical compounds occurring in the marine environment. is the correct one as it involves the use of chemical compounds from marine animals, plants and even the debris of the seafloor so as to produce medicine. Hence, it involves the implementation of biotechnology for medical science.
