Major Achievements in Biology

Researchers and scientists are always intrigued by biological processes and activities, and strive to utilize them for benefit of mankind. Antibiotics, monoclonal antibodies, vaccines and several therapeutic agents, high yielding as well as disease tolerant plants and animals are all results of extensive research in the fields of cell and molecular biology, immunology, biotechnology and genetic engineering. Treatment to several diseases, even genetic disorders are available today only due to breakthrough discoveries in biology. Three such important discoveries are revelation of structure of ribosomes through X-ray crystallography, identification of tumor specific antigens (TSA) expressed on the surface of cancer ...

strains?” Researches on viruses have been carried out since time immemorial. Several vaccines, therapeutics, and targeted drug delivery systems have been developed only through extensive research on virulent strains. However, genetic engineering and molecular biology techniques have enabled scientists to manipulate, and develop new recombinant strains that may not occur in nature spontaneously. Proper containment of these engineered strains is essential as they might have properties that are entirely different from their parent strains. In September 2011 a researcher from Erasmus Medical Center, Rotterdam revealed how he had engineered avian influenza strain H5N1, and made it “more receptive to ...
