    arguments supported the keto form. This form allowed Watson to experiment more with the bonding between the bases to see which way the bases would fit together in order to form the correct width of the molecule. Watson eventually ended up pairing adenine with thymine and cytosine with guanine, and Donohue checked this theory to confirm that these pairings made sense chemically. Without Donohue’s chemical knowledge, the discovery of DNA structure might have been greatly delayed. A great amount…

    World War II is coming to an end and the race begins to discovered the structure of DNA. It’s May 1st, 1952 in a London lab an x-ray camera is clicking off 100 hour exposure of something called DNA. When developed this photo will show the structure of DNA. This photo will explain the blueprint of all life, and how DNA is passed on from generation to generation. Francis Crick and an american scientist James Watson will be in the race for discovery of the century, along with 31 year old British…

    Lombard (90) notes that biotechnology is the use of organisms and their products for commercials purposes. It is the basic fundamental principle of genetic engineering as it entails the genes transfer of various methods in production of recombinant proteins, transgenic plants and animals for commercial applications. In nutshell, genetic engineering is the driving force of biotechnology industry in the world .In this filed, there are two areas of interest, that is production of beneficial enzymes…

    In the 1920s, the field of genetics saw many groundbreaking discoveries. The research of scientists such as Thomas Hunt Morgan and Hermann Joseph Muller proved the existence of chromosomes and genes as well as showed how mutations can be influenced and passed on to offspring. Geneticists from this decade used study results to form a more complete understanding of previously constructed theories. Genetic research in the 1920s significantly advanced scientific thinking and understanding…

    A Comparison of Protein Synthesis between Eukaryotes and Prokaryotes The different fundamental organisation of genetic material and organelles between eukaryotes and prokaryotes leads to dissimilar processes of protein synthesis. The larger eukaryotes have a more intricate pathway associated with protein synthesis, due to both the biochemical structure of organelles and enzymes, and also the transport of genetic material within cell. In this essay I hope to explore the differences of gene…

    For the Carleton Prize for Biotechnology, I would like to nominate the brilliant scientist Rosalind Franklin. Her crystallographic work at King’s College, London was a crucial contribution to the double-helix model of DNA discovered by James Watson and Francis Crick (Gregory, 2002). Her contributions to the scientific community are still being quoted today and without the discovery of the structure of DNA, present day scientific projects such as The Genome project would not have been possible…

    An insight in the biophysical properties of bio macromolecules Natural biopolymers such as nucleic acids, proteins and carbohydrates are essential for life as we see it today. It is incredible to think how this vast set of molecules that are in every living thing, from bacteria to human beings, are mostly made up by six elements (carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus). These biopolymers have the properties to, from small monomers, build giant tridimensional structures with a…

    General Description Huntington's disease is a disease that causes the progressive breakdown in the brain. Huntington's disease can have a major impact on a person's functional abilities and usually results in movement, and thinking and disorders. Every one out of 10,000 people have Huntington’s disease in the world but in the United States, almost 30,000 people have Huntington’s disease. People with Huntington's disease usually develop signs and symptoms in their 30s or 40s, but the major parts…

    There are over a thousand genetic diseases around the world, and Sickle Cell Disease (SCD) is one of those thousand. SCD affects seventy thousand to eighty thousand Americans. “Estimated one in five hundred African Americans and one in one thousand to one thousand four hundred Hispanic Americans have inherited SCD,” (Sickle Cell Disease.) Sickle Cell Disease is inherited by the parents, has symptoms, affects the body, and can be treated. “SCD is inherited in autosomal recessive,” (Single Gene…
