Bioluminescence

Plasmids are extra chromosomal DNA within some bacteria that exist as circular structures. Although they are not essential for survival of the bacterium, they often do confer many environment advantages such as antibiotic resistance. One bacteria of interest is E. coli, a gram-negative organism that is part of normal human gut flora. Some strains of E. coli are pathologic to humans, however some strains are beneficial. For example, one strain produces vitamin K, an essential nutrient. In this…

the agar plate containing the pUC18 plasmid (Fig 2: top left) should have had similar results to the agar plate containing the lux plasmid (Fig 2: middle right), meaning there should have been both lawn and colonial growth, minus the chance of bioluminescence. When in reality, the agar plates taken from the experiment did reveal colonial growth but for the wrong reason. The growth seen in this agar plate (Fig 2: top left) was of another type of bacteria, possibly airborne bacteria that could…

it in the newspaper, Lucy sets off to see the monstrous beast. However it's not because Lucy is eager to see the elephant dead. It's much more than that. Lucy is keen to see 'bioluminescence', light visible in the elephant flesh. This idea would seem bizarre in the C19th. No one would want to look for 'bioluminescence' in rotting foul elephant carcass. However it's not so bizarre…

This article discusses the research behind the bioluminescent millipedes. These rare species are classified as Motyxia. Paul Marek is an entomologist who was determined to find these rare millipedes near San Luis Obispo, California. Marek set out on his journey in 2013. Bioluminescent millipedes are fluorescent, meaning they glow a green hue under UV light. Marek found it easier to search for the millipedes during the night. Soon after arriving at his location he found three bioluminescent…

- Living organisms can manipulate when they illuminate by managing their chemistry and mind forms upon on their prompt needs, whether it’s a supper or a mate - Majority of bioluminescence produced in the ocean is in the form of a bluish-green light - This is because of hues being shorter wavelengths of light, which can go through (and therefore be seen) in both shallow and vast water - Light going from the sun of longer wavelengths…

Abstract Many number of medicines, like growth hormones and insulin, are a possibility because of techniques like transformation of genetically engineered bacteria. Although, manipulating bacterial gene expression has many great implications, it can also be quite harmful. By manipulating gene expression of bacteria, such as Escherichia coli, scientists now have the capacity to help bacteria survive changes in their environment and provide an evolutionary advantage. The present study was…

remind me that there is heat everywhere, only less in some places than others. Cure for Several Ailments, Including Perh aps Loneliness Let an introvert love you. She need not be pretty or kind. She need not even be warm. She must, however, sing bioluminescence in moth form, sing inherence as the wings leave her mouth. Before or after you make love, rest your head on her n arrow bare back as she lies there, head turned away from…

Purpose: To study the expression of the Vibrio fischeri luciferase operon in Escherichia coli (E. coli) by isolating and purifying a plasmid from E. coli, determining its orientation with respect to the plasmid backbone by restriction mapping, and transforming it into an alternate E. coli strain. Methods: Each individual received either E. coli A or B strain of pKN800 plasmid DNA. The plasmid was purified and isolated, then cut with PstI restriction enzyme to create a sample of PstI-cut and…

The bathypelagic zone doesn’t get any light. The animals most commonly found are fish, mollusks, crustaceans, and jellyfish. Red and black are the predominant colors of animals that live here and any bioluminescence is usually blue since red isn’t visible at these depths. 3. The division between the supralittoral (above high tide) and littoral zones. The Supralittoral zone outlines the stretch above the high water level; seawater penetrates the elevated…

Spend some time observing any ocean ecosystem and you will see that it can look like a very dreary place. A place full of hunting, killing, manipulation, fearfulness and harsh living environments. Nevertheless, the species involved in these interconnected ecosystems of the oceans have found ways to survive in these environments by each fulfilling a specific niche. The niche of some of these species is oftentimes accompanied by another organism, however, these relationships are termed as a…
