    646 Words  | 2 Pages

    Model organisms Model organisms are organisms used in the study of genetic fundamental processes, serving as models for certain species and being studied by a community of scientists. One of their main characteristics is that they own some features that make them easy to be used in genetic experiments and can be breed in laboratories. Using them, there can be obtained information about species that cannot be studied directly (like humans). They have a simple structure and they are used to study

    During the course of the past thirty years, the study of model organisms has become more significant in the study of embryological development. A model organism is a species that is easy to cultivate and monitor in a laboratory environment and is used to represent broad groups of organisms. Examples of successful and important model organisms include the Ascidia, Zebrafish, and Medeka species. Through intense researching of these organisms, scientists have been able to gain valuable insight into

    A model organism is a non-human species that is extensively studied to understand particular biological phenomena. The observations are expected to provide insight into the workings of other organisms. When we study disease, development and genetics in biology, they need to be studied in vitro to see how these processes (i.e. pathways and signals) work. Studying these in humans could be considered unethical or unsafe, and very expensive. Model organisms provide insight that we can’t gain from lab

  • Drosophila Essay

    Drosophila and the cinnabar Gene Drosophila melanogaster, commonly known as fruit fly, is mainly used as a human disease model organism for genetic analysis. It was during the 20th century that D. melanogaster was considered as the most significant model organism. D. melanogaster is small in size, and it has a short life span with a good reproduction rate, perfect for raising in large number and generation counts for genetics experiments. Additionally, it has a small genome which makes it easier

    “Animals may be complete organisms, but they are the wrong ones.” Gericke, Corina. “Why animal experiments are not necessary.” According to Dr. Med. Vet. Gericke, Corina, “It is difficult to predict whether a human will react identically or differently based on the results of experiments conducted on animals. The diseases animals contract are much different from ours. And since most human diseases do not occur in animals, their symptoms are simulated using model organisms and have nothing in common

    The development of the heart is a complicated process that implicates cell specification and differentiation, including tissue formation, shaping and alteration, to create a functional organ. The zebrafish has become a potential model system to disentangle the fundamental genetic, molecular, and cellular mechanisms of cardiac development and function. The liver is one of the essential organ in mammals. It performs many functions such as help the body digest food, store energy, and remove poisons

    1313 Words  | 3 Pages

    INTRODUCTION Caenorhabditis elegans are nematodes that are feed on Escherichia coli. and live in free-living soil. C. elegans make good model organisms because they are small, they have a short life span, they reproduce quickly and have many offspring, they are easily and inexpensively grown in a laboratory, there is visible phenotypic differentiation between different genotypes, and there is much known about their genome. C. elegans have most major types of differentiated tissue which include; nerve

    Laboratory Animals shows that over 80 HIV/AIDS vaccines that worked in nonhuman primates were unsuccessful in human trials. In a 2004 study in the journal Stroke, over 4,000 studies report the intended result of more than 700 treatments of stroke in animal models. Although, none of the approximately 150 of these treatments tested in humans showed clinical benefit. This was recorded in a 2005 paper in the International Journal of Neuroprotection and

    For centuries, animals have been known as man’s companions, a form of therapeutic relief, and a source for human joy and entertainment. However, animals are being tortured and treated cruelly for the sake of human prosperity all over the country. Animal testing as a means of researching medical advancements and product quality for consumers is a large problem in today’s society. The research experiments executed with animals in the name of scientific discovery call into question the compassion and

    The term animal testing refers to procedures performed on living animals for purposes of research. The testing is used to research basic biology and diseases, to evaluate the efficiency of new medicinal products, and test the human health and environmental safety of consumer and industry products such as cosmetics, household cleaners, food additives, pharmaceuticals and industrial chemicals. All procedures, even those classified as “mild,” have the potential to cause the animals physical as well

  • Animal Model Essay

    animal model is a living, non-human animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the added risk of harming an actual human. The animal chosen will usually meet a determined taxonomic equivalency to humans, so as to react to disease or its treatment in a way that resembles human psychology as needed. Many drugs, treatments and cures for human diseases have been developed with the use of animal models. Animal

    Animal Research The idea of animal testing has been a contested moral issue for over centuries. Many people have heard the phrase “ animal testing “ but are perhaps still unaware what exactly is involved. According to Biology-Online Dictionary, “ Animal testing is the use of animals in experiments and development projects usually to determine toxicity, dosing and efficacy of test drugs before proceeding to human clinical trials.” In my opinion, I strongly disagree with the concept of animal testing

    Canary in the kitchen detects carbon monoxide! Animal testing must be banned for unnecessary tests. Animals should not be guinea pigs. Animals still feel the pain when they are injected with medicine just like humans. Humans can defend themselves and stop the pain, but the animals get strapped down and cannot move. It is better to have tests run on animals because animals will help find cures faster. Animal testing must be banned for unnecessary tests because a lot of animals are dying for no reason

    Animal Testing in Medicine: The Truth Behind the Propaganda What if you were told that today’s new drugs are yesterday’s news? What emotion would it stir in you? Every year the production of dozens of promising new medications are delayed, sometimes indefinitely, seemingly without a second thought. Was a major flaw found? No. Surprisingly, the delay hinges on the copious amount of animal testing that must be successful in each round before the drug reaches the stage where human trials are acceptable

    The answers of many questions that trouble us can be found by doing first hand investigations. In science, first hand investigations allow scientists to discover new things and explain old things. Through these, they are able to form hypothesises, models, experiments, theories and even laws. First, when observations are made, hypothesises are formed. To test these hypothesises scientists conduct experiments. If their hypothesis is right, it is confirmed by further experiments and validated by other
