Genetics With Drosophila Flies Josh Derrall Lab Group: Dana Gilkes James Lupo Olivia Giannola December 4‚ 2012 Prof. Hunter Introduction Genetics is a topic that has been studied for hundreds of years. One of the most notable geneticists was Gregor Mendel. Mendel studied basic inheritance patterns and gene expression using pea plants. Mendel determined that the offspring of two parents contains one gene from each parent (McKusick 1983). However‚ since Mendels discoveries

response to a socio-scientific issue. The use of IVF and preimplantation genetic diagnosis (PGD) Preimplantation genetic diagnosis (PGD) is the process of identifying genetic defects within an embryo before implantation‚ PGD allows the embryos DNA to be studied for mutations and genetic diseases. Originally PGD was used on female embryos and was used to prevent pregnancy termination in pregnancies with high risks of a sex linked genetic disease. Process The IVF procedure consists of ovarian stimulation

DROSOPHILA GENETICS DROSOPHILA CULTURE We will study basic principles of Mendelian inheritance with the use of the fruit fly‚ Drosophila melanogaster [the name means “black-bodied fruit-lover”]. Drosophila was one of the first organisms to be studied genetically: its small size‚ short life cycle (10 ~14 days at 25oC)‚ high reproductive rate (an adult female can lay 400-500 eggs in 10 days)‚ and ease of culture and genetic manipulation have made it perhaps the best understood animal genetic system.

approach to abnormality The biological model compares abnormal behaviour with a disease. It assumes that all mental illnesses have a physiological cause related to the physical structure and brain. Doctors diagnose mental illness using well-established criteria. Psychiatrists also use diagnostic manuals for mental illness and compare symptoms with set classifications of illnesses. According to the biological model‚ mental illness is caused by one or more of the following factors; genetic inheritance

Is anti-social behaviour a result of genetic inheritance or your environment and upbringing? The debate of the cause of anti-social behaviour has been ongoing for many years between scientist’s‚ professionals and the general public. Experts disagree over whether genetics‚ environment or home life plays the greater role in anti-social behaviour. The general opinion over all of why people turn to violence and anti-social behaviour focuses on family breakdown‚ drug and alcohol abuse‚ poverty‚ unemployment

And Genetic Technology Should We or Shouldn’t We? SCI 115 Some believe that personalized medicine is the wave of the future‚ while others believe it is tampering with the livelihood of human existence. Is this the key to future cures for disease or is this the door to ending our existence as we know it? Researchers have argued the pros and cons of personalized medicine and genetic testing. Let’s begin by getting an understanding of personalized medicine and genetic testing.

EXPERIMENT OBJECTIVE: The objective of this experiment is for students to gain handson experience in the principles and practice of Polymerase Chain Reaction (PCR). BACKGROUND: Polymerase Chain Reaction (PCR)‚ discovered by Kary Mullis‚ has had an extraordinary impact on various aspects of biotechnology. PCR has revolutionized research and diagnostics-based molecular biology. PCR

Albinism Background Information Albinism is a genetic disorder which affects the amount of melanin produced‚ in a person’s skin‚ hair‚ or eyes. Oculocutaneous albinism‚ Ocular albinism‚ and Hermansky-Pudlak syndrome are other names for this genetic disorder. The disorder affects mostly men‚ because it is a recessive gene. Females are usually carriers. Albinism does not affect any specific ethnic or religious group. Symptoms/ Effects This Genetic Disorder affects the eyes‚ skin‚ or hair’s pigmentation

Genetic Diversity In Agriculture Genetic variation is the raw material for the plant breeder‚ who must often select from primitive and wild plants‚ including wild species‚ in search of new genes. The appearance of new diseases‚ new pests‚ or new virulent forms of disease causing organisms makes it imperative that the plant be preserved‚ because it offers a potential for the presence of disease resistant genes not present in cultivated varieties. Also‚ there are demands for new characters-- for

Genetic engineering is a type of engineering where genes are modified to find cures‚ diseases‚ and more. Genetic engineering uses the central dogma‚ which is the idea of taking. DNA transcribing it into RNA translates it into protein and expressing it as a trait. Recombinant plasmids are when DNA fragments are inserted into a plasmid vector. The recognition site is where the plasmid gets cut by the restriction enzyme which is an enzyme that cuts a DNA molecule. Recombinant DNA is the DNA being inserted
