11th Class Biology The Living World / जीव जगत Science and Technology

Scientific investigations may be basic or applied. Inventions of new technology extend new hopes and open avenues for the work and research which was not possible earlier. Discovery of radioactive isotopes enabled tracing metabolic pathways, development of microscope and then electron microscope provided useful tools to study biology. X-ray crystallography helped in the study of the structure of DNA, protein and many other biomolecules. Biotechnology and genetic engineering are fruitful due to accumulation of knowledge from different sources. It is note worthy that while information gathered from basic researches enriched the field of applied researches, the fruits of applied researches contribute to explore and widen the area of basic researches.
