Louis Pasteur: Remembered for his breakthroughs in the causes and preventions of diseases. He also created the first vaccines for rabies and anthrax. Gregor Mendel: Founder of the science of genetics. Charles Darwin: He established that all species of life descended from common ancestors and proposed the scientific theory that evolution resulted from natural selection. Jean-Baptiste Lamarck: He was an early proponent of the idea that evolution occurred in accordance with natural laws.
It is here where Watson meets another biologist by the name of Francis Crick. Interested in the same topic; both scientist team up at Cavendish lab in Britain where Crick was working, and they started working together. On the other side of this race are two scientists by the names of Rosalind Franklin and Maurice Wilkins. Under the authority and supervision of Franklin, major steps to apply the technique of X-ray diffraction to DNA research are conducted at King’s College in London. The two often find difficulty in working together and their chemistry isn’t as strong as Watson and Crick’s despite getting more done.
These organelles are believed to have been absorbed in early pre-eukaryotic cells and ultimately developed a symbiotic relationship with the host cell over time. Essentially, mitochondria and chloroplasts are thought to be distant relatives of ancient, free-living prokaryotes, that sometime in the past, they were cells themselves. There is compelling evidence supporting this hypothesis. Bacteria routinely absorb other smaller bacteria and sometimes these are not fully digested. This is one of the main pieces of evidence used to support endosymbiosis.
He is the first scientist to record precise descriptions of fungi, protozoa, and bacteria (“Microbiology’s”). Louis Pasteur postulated the germ theory of disease which states “microorganisms are the causes of infectious disease. While Pasteur could not prove his theory, another scientist by the name of Robert Koch was able to. Procedures known as “Koch’s postulates” are principles that link microorganisms to specific diseases. The “Golden age” of microbiology occurred in the late 1800’s, this is when many infectious diseases were identified (cliffsnotes.com).
Biochemistry Article Review The Proof Is in the Proteins By: Katherine Harmon My article The Proof Is in the Proteins outlines how Douglas Theobald an assistant professor of biochemistry of Brandeis University took the idea of there being a single ancestor to all other organisms and proved this old-age Darwinian theories likelihood. This theory comes from Charles Darwin who fathered the theory that all species of life came from one common ancestor evolving over a period of time. This theory is one that many researchers and biologists base there own work around. Many people think it may already be obvious that many life forms grew from one single organism because of the fact that we have discovered and dissected DNA and its genetic heritage. With the discovery of DNA in the mid-20th century it established this idea in popular and academic rings
Even though Avery’s experiments clearly indicated that genetic material is composed of DNA, most scientists at that time continued to suspect that proteins were the genetic material. ____ 3. Bacteriophage are a type of bacteria that infects viruses. ____ 4. Hershey and Chase were the first two scientists to prove that genetic material is composed of proteins.
They proved that progression in this field of study can have vast as well as monumental improvements in contemporary science and technology. Eugenics and Frankenstein both included advanced ways of thinking and study. However, with advancement, setbacks can also follow. In both cases, the development of the ideas of Eugenics and creation of Frankenstein’s monster were thought to be ideas that would revolutionize scientific thinking and bring the ability to even further the scientific field of study. This statement was proven to be precise.
Student: Gigi E. Ginis Course: BITC 1350 – Fall 07 Teacher: Dr. B. Kirkpatrick Title: Gene Therapy Gene Therapy Gene therapy, which first came to light in the early 1950s, is a technique based on the idea that the treatment can replace or kill the genes that are causing genetic diseases. For years since the first mention of “gene therapy,” scientists have been on the mission to identify and map the entire genome and figure out the specific genes that are the cause of diseases such as arthritis, Alzheimer’s, cardiovascular diseases, and cancer. Scientists believe that if they can pinpoint the affected genes and use this therapy on the defective genes, some of these diseases and conditions can be prevented.
If Neanderthals ever walk the earth again, the primordial ooze from which they will rise is an emulsion of oil, water, and DNA capture beads engineered in the laboratory of 454 Life Sciences in Branford, Connecticut. Over the past 4 years those beads have been gathering tiny fragments of DNA from samples of dissolved organic materials, including pieces of Neanderthal bone. Genetic sequences have given paleoanthropologists a new line of evidence for testing ideas about the biology of our closest extinct relative. The first studies of Neanderthal DNA focused on the genetic sequences of mitochondria, the microscopic organelles that convert food to energy within cells. In 2005, however, 454 began a collaborative project with the Max Planck Institute
Biomimicry, one great invention. “I think the biggest innovations of the twenty-first century will be the intersection of biology and technology. A new era is beginning”. (jobs, 2011) (Stafford, 2011). The intersection between biology, the nature, and the technology is known as Biomimicry.
