Model organism

ventriculi, yielding about 15 % of the total dry cell mass (Bellamy, 1974). The most effective producers of cellulose are Acetobacterhansenii (Park et al., 2003), A. xylinum (Junaidi et al., 2012; Hungund et al., 2013),). A. xylinum has been applied as model bacteria for applied and basic studies on cellulose production because it can produced relatively high levels of polymer from a wide range of carbon and nitrogen sources (Bielecki, et al.,…

Caulobacter Crescentus is a dimorphic, α-proteobacterium found in oligotrophic environments. Their dimorphic cell cycle produces two morphologically and functionally different daughter cells, known as the stalked cell and the swarmer cell. The stalked cell remains anchored to the substratum and is sessile, while the swarmer cell is motile. Upon chemotaxis, the swarmer cell disperses in search of nutrients. Once sufficient nutrients are located the cell cycle can continue. In the early phases of…

Some forty years ago, there was a scientist credited with building the model of Neo-Darwinism, who was Theodosius Dobzhansky. Science lives through constant changes in secular theories and society about the beginning of the universe and of life on Earth, which give way to the idea of existentialism. Through some research, I found that he is best known for one his evolution paper, called Nothing in Biology Makes Sense Except in the Light of Evolution. Dobzhansky states in the article his three…

be done in genetic engineering and cloning technology precisely. As highlighted by (Giassetti* et al, 2013), “genetic engineering is widely used at various branches of medicine to produce vaccines, monoclonal antibodies, animals that can be used as models for diseases or to be used as organ donors”. Through genetic engineering, cloning technology can develop the medical field which many various type of medicine can be produced in order to cure various type of diseases. In short, cloning…

The circadian clock regulate the biology and behavior of a living organism throughout a day (about 24 hours). It can be affected by external factors such as daylight or darkness of the environment. The circadian system can modify the behavior and physiological functions to adapt the environment. For mammals, the suprachiasmatic nucleus (SCN) are the central circadian clock of our body, which is located in the hypothalamus. Meanwhile, there are peripheral circadian clocks which located in most…

the mealworms in on-farm feed preparation is most likely justified especially the production of the mealworms could be achieved on small farm level. Away from its possible use in pet or aquaculture systems, Tenebrio molitor is being used as a model organism in biology laboratories for biology, biochemistry, evolution, immunology, and physiology. This is based on their relatively large size as well as the ease in their production and…

Introduction In this study, we explored the concept of different habitat utilization at different life stages using a species of Buckeye butterflies known as Junonia Coenia. The concept of habitat utilization is known as the way organisms make use of the resources in their habitat for successful reproduction and a way to avoid predators. The main objective of this study was to determine if larvae and adults would be found at the same height and distance on the host plant and to compare their…

The commitment of this research project is to comprehend the essential elements of the development of the personality trait cooperation. As noted, this research will also provide the evolutionary explanation for how cooperation manifested through sociobiological function. It intends to communicate the consequences of self- interest and collaborative behavior; likewise, how does the cooperative trait benefit an individual socially and independently and whether natural selection reveals a…

evolution could have occurred which was proposed by Charles Darwin. The Darwin’s theory outlines that characteristics favorable to the reproduction and survival of organisms in their environment will be selected for, over time, new species will appear in response to environmental changes. OBJECTIVE To plan a first-hand investigation to model natural selection with an…

their function of moving substances in and out of cells. Prokaryotic and Eukaryotic cells are two very different, but also very similar cells. There are many differences between them that can help to associate between each one. Eukaryotes are any organism that consists of one or more cells that have DNA in a membrane-bound nucleus.(En.wikipedia.org, 2017) A eukaryotic cell is a large, more complex cell compared to a prokaryote. Inside a eukaryote, consists of many different organelles, all with…
