Determining The Phylogenetic Relationship Of A Collection Of Hydra Strains And Species Using The Mitochondrial Genes : Lrrna, Trna-Trp And Coii, Jacob Zuckman
Theses, Dissertations and Culminating Projects
The discovery of the mitochondrial DNA (mtDNA) in the early 1960’s ushered in the field of organellar genetics. Evidence from both genetic and physical techniques has demonstrated that mtDNA are generally circular in structure, and that they represent the vestigial structure of the ancestral prokaryotic endosymbiont genome (Nosek et al., 1998). The more than 90 vertebrates and invertebrates sequenced to date have been found to have a remarkably constant gene content. With few exceptions, each contains the genes for 13 energy pathway proteins, the 2 RNA components of mitochondrial ribosomes (23S and 16S rRNA), and 22 transfer RNAs (Pont-Kingdon et …
Fluorescent Photoinduced Electron Transfer (Pet) Cation Sensors Derived From Natural Products, Kenny Loo
Fluorescent Photoinduced Electron Transfer (Pet) Cation Sensors Derived From Natural Products, Kenny Loo
Theses, Dissertations and Culminating Projects
Two new second generation fluorescent switches that are based on the chromophore-spacer-receptor architecture are reported in this thesis. The fluorescence modulation of these switches is a result of quenching or initiating photoinduced electron transfer (PET) between the chromophore and the receptors due to cation binding. These two molecules utilize an alkaloid, anabasine, as the proton receptor, and function as fluorescent off-on-off switches with decreasing pH. One of these molecules also utilizes a coumarin as the chromophore, making it the first rationally designed fluorescent PET system based on natural products. Further studies of two well-known first generation fluorescent switches to achieve …
Ecology Of The Plankton Of Lakes Wapalanne And Ocquittunk In Sussex County, New Jersey, Malgorzata Barbara Drazek-Falah
Ecology Of The Plankton Of Lakes Wapalanne And Ocquittunk In Sussex County, New Jersey, Malgorzata Barbara Drazek-Falah
Theses, Dissertations and Culminating Projects
The diversity of planktonic organisms was studied for seven months in Lake Wapalanne and Lake Ocquittunk (Stokes State Forest), Sussex County, New Jersey. Relative abundance and species diversity were studied as well as water quality including parameters: temperature, pH, dissolved oxygen, conductivity and depth of lakes. The data of seasonal changes in abundance of organisms and water quality was compared between both lakes.
Three stations were set up along the straight line on Lake Wapalanne, buoyed by diatometers, which were used for diatom collection. There were also three stations located along the sides of Lake Ocquittunk arbitrary picked. Plankton samples …
International Students’ Perceptions Of Food Service At A New Jersey State University, Rebecca Ann Schubert
International Students’ Perceptions Of Food Service At A New Jersey State University, Rebecca Ann Schubert
Theses, Dissertations and Culminating Projects
The aim of this study is to explore international students’ perceptions of food service at Montclair State University. Twelve international students were recruited to participate in this quick ethnography. Seven of the twelve participants were males and five were females. Students came from a variety of ethnic backgrounds including Asian/Pacific Islander, African, Hispanic and White, non-Hispanic. Inclusion criteria were that the students must be considered international students by the university and must be able to effectively communicate in English. The students completed a fourteen-question survey questionnaire which asked about demographic data as well as questions about attitudes and beliefs about …
The Effects Of Heavy Metals On The Cyanobacterium, Anacystis Nidulans, Suzen Sameer Awad
The Effects Of Heavy Metals On The Cyanobacterium, Anacystis Nidulans, Suzen Sameer Awad
Theses, Dissertations and Culminating Projects
Anacystis nidulans is a rod-shaped, freshwater cyanobacterium. Like other cyanobacteria, it is an obligate photoautotroph that is similar to gram-negative bacteria in cell wall structure, replication and ability to harbor plasmids. Anacystis nidulans is often used as an indicator of the presence and level of pollutants in the environment. Mercury, iron, cadmium, and zinc are among the heavy metal contaminants found in the environment and in bodies of freshwater through industrial discharges, agricultural runoff and sewage treatments. In very low concentrations, they do not pose any threat to the environment, but high concentrations can be lethal. Different microorganisms vary in …
