It becomes a seminal technology for studying the structure of DNA. It is used for patients with non-Hodgkin's lymphoma. Development of Biotechnology. French scientists discover messenger RNA (mRNA). Dr. J. Craig Venter and his team replicate a bacterium's genetic structure entirely from laboratory chemicals, moving a step closer toward creating the world's first living artificial organism. Biotechnology has developed by leaps and bounds during the past cenBiotechnology has developed by leaps and bounds during the past century.tury. The FDA clears a DNA microarray test system, which aids in selecting medications for a variety of conditions. Such variations in DNA are called restriction fragment length polymorphisms and are extremely useful in genetic studies. The first automatic gene machine, or gene synthesizing machine, is developed in California. This is an important step toward personalized medicine. In 1988, the drugs are used to treat Kaposi’s sarcoma, a complication of AIDS. The late nineteenth century … Cloning of the gene that encodes human lung surfactant protein is accomplished. Yeast genes are expressed in E coli bacteria. The U.S. National Institutes of Health (NIH) forms a Recombinant DNA Advisory Committee to oversee recombinant genetic research. The FDA approves a diagnostic serum tumor marker test for ovarian cancer. The first vaccine for rubella is developed. • By the last decades of the 20th century, biotech became a The FDA approves the first therapeutic antibody to treat cancer in the United States. The FDA approves first biotech-derived interferon drugs to treat cancer. Harvard researchers report building “lung on a chip” – technology. Trachea derived from stem cells transplanted into human recipient. A group of scientists sequence the complete genome of a complex organism, Saccharomyces cerevisiae, otherwise known as baker's yeast. main heads namely, Chromosomal Basis of Inheritance: Summary, Chromosomal Basis of Inheritance: Evaluation, Principles and Processes of Biotechnology, Traditional Biotechnology: Fermentation, Single Cell Protein (SCP), Transgenic Plants / Genetically Modified Crops (Gm Crops). Dr. Luc Montagnier of the Pasteur Institute in Paris isolates the AIDS virus. The first artificial chromosome is synthesized. These enzymes cut DNA into pieces and are used for various studies and applications. PCR is recognized as the most revolutionary molecular biology technique of the 1980s. Chemists in Japan create the first DNA molecule made almost entirely of artificial parts. This is a major step toward reducing premature birth complications. Neuralstem initiates clinical trial using human embryonic stem cells to treat patients suffering ALS (Lou Gehrig’s disease). Science and Nature magazines publish the human genome sequence, making it possible for scientists all over the world to begin researching new treatments for diseases that have genetic origins, such as cancer, heart disease, Parkinson's and Alzheimer's. The FDA approves a recombinant protein to treat multiple sclerosis—marking the first new multiple sclerosis treatment in 20 years. The purified enzyme reverse transcriptase is first used to synthesize complementary DNA from purified messenger RNA in a test tube. FDA approves a personalized prostate cancer medicine that boosts a patient's immune cells to recognize and attack the cancer cells. Colony hybridization and Southern blotting are developed for detecting specific DNA sequences. The development marks the first use of mammalian cells (monkey kidney cells) and the first application of cell culture technology to generate a vaccine. This marks a technological breakthrough in gene expression and DNA-sequencing technology. A multitude of genes, human and otherwise, are identified and their functions described. The NIH approves guidelines for performing experiments in gene therapy on humans. This shift precipitated a rash of startup companies, starting with the founding of Cetus (now part of Novartis Diagnostics) and Genentech in the mid-1970s. The entire genome of the HIV virus is cloned and sequenced. The FDA approves a bioengineered form of the protein interferon gamma to treat chronic granulomatous disease. The first genetically engineered vaccine is developed for hepatitis B. Scientists at the Institute for Genomic Research complete the first full gene sequence of a living organism (other than a virus) for the bacterium Haemophilus influenzae. The first baboon-to-human bone marrow transplant is performed on an AIDS patient. The development marks the first use of mammalian cells (monkey kidney cells) and the first application of cell culture technology to generate a vaccine. The complete genetic code of the human chromosome is deciphered. "As main outcome of the UN Earth Summit held in Rio in 1992, Agenda 21 calls for a global partnership able to address the problems of the present and prepare the International Community for the challenges of the upcoming century. With the adoption of Resolution 47/191, the General Assembly agreed on the creation of the Commission on Sustainable Development. 1957 Scientists prove that sickle-cell anemia occurs due to a change in a single amino acid in hemoglobin cells. The first vaccine for meningococcal meningitis is developed. 1. The development of a second generation of perennial, woody energy crops, and the improvement of the efficiencies of biorefineries, will likely shift the economic balance towards more economically competitive applications of biofuels. its products and applications.
