competent and compassionate medical care, and enable me to be proud of the system I would serve. My undergraduate honor’s thesis on the effects of disrupted copper homeostasis and exposure to pesticides DDT and DDE on Alzheimer Disease phenotypes in Drosophila models, my graduate work in the humanities, and my extensive clinical experiences make me an ideal candidate with a broad set of knowledge and…

Subsequently, other families of GFP variants were discovered and GFP mutants were engineered. These families of GFP-like proteins were discovered in a class of non-bioluminescent Anthozoa (corals). These GFP-like variants have differing properties with regards to chromophore, excitation and emission wavelengths (Tsien & Tsien, 1998) e.g. red & later in other coral species - yellow, cyan and orange. The only other species that fluoresces green is Renilla reniformis (Matz et al., 1999).…

to less than 5 percent of the entire genome. Most of the rest is made up of several types of noncoding repeatitive elements.The relative percentage of non repetitive DNAin bacteria is 100% and decreases in the higher developed eucaryotes,70% in Drosophila and 55% in animals and 33% in plants. Most gene sequences are unique, found only once in the genome. In contrast, repetitive DNA elements are found in multiple copies, in some cases thousands of copies, unlike genes, most eukaryotic genomes…

Morgan, n.d.). He then became Professor of Experimental Zoology at Columbia University in 1904. Morgan had a very keen sense towards teaching. He is also known as being a successful teacher. He began to research sex linkage on the fruit fly, or Drosophila, in 1909. Before his discovery, the world had thought that the chromosomes were fully formed adults already present in the egg or sperm. People did not have the knowledge to test that theory, until Thomas Hunt Morgan began to research the…

Fruit Flies - Trade Barrier for Mangoes Mango- often called as King of all Fruits. When Mango is there, anyone hardly asks for any other fruit. Mangoes are famous for their flavor, juice, color and fragrance. Mangoes vary in sizes and color. The colors might be yellow, orange or even red or green when ripe. Different varieties of Mangoes may taste differently and have different textures. Mango is the fruit of tropical and sub tropical zones. Asia falls into this climatic zone, thus this…

central to our overall understanding of learning and memory were established using Aplysia. For instance, the role of the cAMP signaling system, or branch-specific storage of memories discovered in Aplysia has also been shown to be important in Drosophila and the mouse [5]. Therefore, it is expected that contributions of the proposed studies will be conserved in mammals. Positive results would offer additional new insights into the mechanisms of memory storage and will have a major conceptual…

can be defined as continuous or meristic. Continuous traits are traits that aren’t able to fall into distinct categories, like weight for example. Meristic traits are traits that can be expressed numerically, like the different number of bristles Drosophila flies have. Both of these types of traits fall under the quantitative traits category of quantitative genetics because they display a range of phenotypic variation that follow a normal distribution pattern. This means that the traits being…

Jongens a faculty member in the genetics department at the Perelman School of Medicine at the University of Pennsylvania. Our research was centered on determining if varying sucrose concentrations affected the weight, survival, and longevity of Drosophila (fruit flies) in comparison to the control flies. As a senior I am completing an independent study project on the motility of microorganisms in soil. Because my experience engaging in research has added a unique dimension to my education, I…

was responsible for creating knee caps as the resulting offspring only had one leg segment. Furthermore, the article explains how accidentally duplicating genes is a mechanism by which evolution can occur. In class we discussed that bar eyes in Drosophila are the result of duplication of the 16 A region. If there was an advantage to having bar eyes, perhaps over time the bar-eyed flies could potentially become their own species. This relates to the article because they have some evidence of…

Utilizing his knowledge in a multidisciplinary experiment with the bithorax mutation in Drosophila, Waddington caused four wings to form in an adult fly rather than the wild type two wings. In the experiment, he used wild type flies treated with ether to produce the mutated phenotype. Next, he performed selective breeding for the phenotype, creating…
