Alfred Day Hershey grew up to become a winner of the Nobel Prize for Physiology or Medicine in 1969 for his world changing genetic discovery. In 1952, at Cold Spring Harbor Laboratory in New York with his research assistant, Martha Chase, through an experiment, discovered that phage DNA enters the bacterial cell and then directs the cell to produce more bacteriophages. This experiment proved that DNA (deoxyribose nucleic acid) is the genetic material of bacteriophages as well as other organisms, opposed to the prior belief that protein was the genetic material of organisms. This discovery had set the groundwork for modern genetic study, which led to pharmaceutical development and possibilities of genetic enhancements.
The study of genetics can be traced back to as far as Gregor Mendel’s pea plant experiments in which he discovered three laws: The Law of Segregation, The Law of Independent Assortment, and The Law of Dominance. His results were published in 1865 but was not acknowledged until much later. “It wasn 't until 1900, after the rediscovery of his Laws, that his experimental results were understood.” (Concept 1 Children Resemble Their Parents). Many other discoveries had been made from the time of the rediscovery of Mendel’s Laws up until Alfred Day Hershey’s discovery of DNA as genetic material. One discovery that was crucial to the discovery made by Hershey years later was the discovery made of bacteriophages made by Frederick Twort in 1915 and Felix d’Herelle in 1917. “Immediately after their discovery, the thought of using phages to fight bacterial infections was already apparent.” (Phages). Without the discovery and theories of bacteriophages, Hershey never would not have been able to make his discovery in 1952. “Alfr...

...n has been expressed regarding its inherent biological and social hazards.” (Genetic Engineering). It may be a long time until scientist completely understand GMOs, but speculations point towards negative results.
The discovery of DNA being genetic material, made by Alfred Day Hershey in 1952, has since been influential in a number of ways. It had set the groundwork of modern day genetics by influencing other major discoveries. It had also made its way to influencing pharmaceuticals and the medical field by using information found in those discoveries to come up with methods for creating medicine and cures. The effect of Hershey’s discovery is still impacting our lives today by giving us the possibility of genetic modification through genetic engineering. Hershey’s encounter with this discovery not only impacted the United States of America, but impacted the world.

Essay on Nobel Prize Laureates in the Field of Medicine and Physiology

- Every year, a prestigious prize is given to people who provide a reason for change, a new invention or a new discovery. The Nobel Prize Laureates in 2013 in the field of physiology, and medicine was given to three individuals. The Laureates were James E. Rothman, Randy W. Schekman and Thomas C. Südhof. The three investigators revealed that there is the machinery that controls how cells transport major molecules in a cargo system which ends up delivering them to the right place at the right time in the body....   [tags: James Rothman, Randy Schekman, Sudhof]

Nobel Prize for Cell Signaling Pathways Essay

- ... There are two processes that are involved in the bulk transport of large molecules. After these large particles are packaged in vesicles, if the molecules are to be secreted from the cell, the transport vesicles fuse with the plasma membrane in a process called exocytosis. James Rothman discovered that “this process is done very precisely as specific protein complexes on the transport vesicles and specific proteins on the plasma membrane bind together to cause this fusion” (1)...   [tags: cell, regulation, genomic, organisms]

Nobel Prize Awarded to Randy W. Schekman, James E. Rothman, and Thomas C. Südhof

- ... Yeast cells, or Saccharomyces cerevisiae, that had mutated transport mechanisms established a genetic basis for vesicle transport and fusion to the plasma membrane. From these cells, it is possible to isolate regulatory genes that encoded proteins essential to intracellular transport. Kaiser and Schekman (1990) specifically analyzed the SEC proteins: manipulation by mutation reveals that construction of vesicles is dependent on SEC proteins, and that vesicles are able to form a COPII coat that contains these SEC proteins....   [tags: cells, vesicles, scientists]

Essay on The Chicken Hall Of Fame

- I am writing you today to nominate a truly influential virologist to the Chicken Hall of Fame. Payton Rous used the chicken to make discoveries and advances in his field that were unparalleled in his time. In fact, his achievements were not even recognized at the time, and for many years his work went unappreciated. It is time that Peyton Rous received the recognition that he deserves; Rous has more than earned a spot in the prestigious Chicken Hall of Fame. Peyton Rous was born in Baltimore in 1879, and although his father died early, his mother stayed in the city and worked to ensure the best possible education for her children....   [tags: Cancer, Oncology, Nobel Prize, Tumor]
