James Watson, Francis Crick, Rosalind Franklin and Maurice Wilkins all played a pivotal role in determining the structure of the DNA molecule. The orderly and methodical work at King’s college, London by Rosalind Franklin and Maurice Wilkins provided a more experimental approach, working closely with X-ray diffraction images of DNA, this was juxtaposed to Watson and Cricks who at their Cambridge lab approached research by building physical models, narrowing down possibilities and producing ever…

How do we know that genes are made of DNA? In the 1920s, scientists agreed that genes are located on chromosomes, and they already knew that DNA and proteins make up chromosomes. They assumed that genes were made of proteins because DNA is chemically simple and proteins are not, but this was proven to be wrong. In the late 1920s, a great discovery was made by Fred Griffith while studying Streptococcus pneumonia (pneumococcus). He found that pneumococci come in a pathogenic form and a harmless…

One of the most shocking aspects of life and etiquette in Elizabethan England is hygiene. Can you imagine living in a world without running water or plumbing? Where bathing was rare and toilets were nonexistent? A world without toothbrushes? These are all things that the people who lived during Shakespeare's lifetime had to deal with. Hygiene has come a long way since 1600. In Elizabethan England, hygiene depended on your social class. You got what you could afford. When considering hygiene in…

Lauren Swain Chemistry Writing Assignment November 25, 2014 DNA Virtually anything can be identified by DNA, also known as Deoxyribonucleic Acid. It is a method of identification of growing and living things. According to genome.gov, a DNA molecule consists of two strands that bind around one another to form a shape known as a double helix. Each strand of the double helix has a backbone made of interchanging sugar and phosphate groups. “DNA sequencing is a scientific technique used to define…

would be in good favor of the general public as they have pure intentions. Individuals would be given more power, more involvement, and more freedoms to make a difference in our society and help diminish automatic government. Unlike another of Howard’s reforms, such as giving more power to the president, the people would become supportive of this reform as they personally benefit and power is given to them and not a single individual. Social acceptance of this reform would be high, it is…

application in low-voltage, high-power traction applications have been introduced [3]-[5]. In these applications, the three-level inverters often need to operate with modulation indices (m) lower than 0.5 [6]- [10]. Additionally, at lower modulation indices, traction drives operating with induction motors (IMs), interior permanent magnet motors (IPMs) or synchronous reluctance motors (SynRMs) may need to provide higher reactive power, thus operating with a lower power factor (pf) [9], [11]-…
