Genetic Causes of Prostate Cancer: A Study

The authors of the study were interested in looking at genetic information in order to determine if there were any variants or covariants of a gene that had previously been linked with an increased risk of developing prostate cancer. Chromosome 17 is the strand of DNA that had been previously linked with prostate cancer. Results of the study indicate that there are two different variants of chromosome 17, and that both of them are associated with prostate cancer. Individuals who are born with those variants are at an increased risk of developing prostate cancer. A side finding of the study is that one of the variants has the opposite impact on type 2 diabetes. Individuals born with that variant are less likely to develop type 2 diabetes. Authors of the study were in...

Genetic Arbidopsis Lab Essay Sample

Genetic Arbidopsis Lab Essay Sample Abstract             The purpose of this lab experiment is to observe the mechanism of the leaf morphogenesis through the characterization and isolation of two mutants of Arabidopsis thaliana. We observed the various characteristics of the wild type Arabidopsis and the mutants. We started with one wild type phenotype (Col), which is round, short and regular with hairy trichome. We also observed and recorded the phenotypes of the two mutants; (gl1) and (CA1). We first crossed the (ColXCA1) and then (ColXgl1) to obtain the F1 seedlings. However, the cross was not successful and we had to wait to get the F1 seedlings from the other students. In the F1 phenotype for (ColXCA1), we found the serrated edges with hairy trichome were domi

Is Genetic Engineering the Future of Life? Essay Sample

Is Genetic Engineering the Future of Life? Essay Sample Main question: ‘Is genetic engineering the future of life?’ Thesis statement: Even though genetic engineering has many benefits, it should not be the future of our lives. This research is being conducted because I have a strong interest in it. At first when we had to choose a book to start our ideas, I picked up any book that I could find. At first nothing really interested me, but then I picked up the book ‘Genetic Engineering’. I flipped through the pages and read some pages here and there and I found it quite interesting. I like this topic because it shows me many advantages and disadvantages that it is hard to chose a side on which to support. I think that learning about something of interest that I know n

What Is the Likely Role of Genetic Transmission in Schizophrenia Essay Sample

What Is the Likely Role of Genetic Transmission in Schizophrenia Essay Sample Schizophrenia has been defined as a “significant loss of contact with reality, often referred to as psychosis” (Butcher, Mineka, Hooley & Carson 2004 p.458). Although schizophrenia is termed as one illness, it is more likely that it is a combination of disorders with “a variety of etiologies, courses and outcomes’ (American Psychiatric Association 1997 p.49). The symptoms of the illness include hearing voices and a conviction that external forces are interacting on the person. An overall disillusionment with life results from these symptoms and tends to lead to detrimental effects on everyday functioning. The causes of this disorder are unclear, however it has been shown to be a combi

Intelligent Drum Machines Using Cartesian Genetic Programming Initial Essay Sample

Intelligent Drum Machines Using Cartesian Genetic Programming Initial Essay Sample 1. IntroductionA musician’s need to express their musical ideas in a way that is both acoustically pleasing and comfortable for whom ever is using it cannot always be communicated by themselves alone and often requires external assistance. This aid often comes in the form of an instrument, an interface channelling the thoughts and emotions from a user into their surrounding environment manifested into a physical medium, for example sound and light. This report will focus in on the acoustic exchange of these ideas and so will be restricted to the musical art form. The technology that is developed as a solution to this problem has been developed with two factors in mind; how it sound

Hemophilia as a Genetic Disorder

Genetic Disorders: Hemophilia Hemophilia is a bleeding disorder in which the blood doesn’t clot correctly, because “a person lacks or has low levels of certain proteins called clotting factors.” (Kahn, April 1.) It is a rare disease and has “Fewer than 200,000 US cases per year.” It is usually inherited by a family member, and can last for years or can be a lifelong disease. There is no known cure for Hemophilia but it is said that treatment can help. The typical gender that is affected by this disorder are males, but females can be too. The usual ages diagnosed with Hemophilia are from birth to the age of 40, and less commonly ages 41 through ages 60+. There are a few causes of this disorder. It can be caused by low factor levels, not having enough clotting factors...

The Impact of Genetic Predisposition to the Development of Substance Abuse

Genetic predisposition is one of three main factors that contribute to the development of substance abuse. According to this, there’s a likelihood for dependency to occur when an individual has a family history of alcohol/drug dependency and their genetic information contains the particular set of genes i.e. coded information found within a person’s DNA, that control addictive behavior, and are expressed when the individual begins recreational drug use and becomes dependent on them. However, a genetic predisposition doesn’t mean that the individual is inherently an addict or that he/she is going to wind up with a substance abuse problem. It is only after certain factors are taken into consideration and the occurrence of a recreational drug habit does the genetic pre...

Genetic Explanations for Aggression Essay Sample

Genetic Explanations for Aggression Essay Sample Early research concentrated on chromosomal abnormalities but no specific genotype has been associated with aggression. Genes determine how much testosterone a person’s body produces and how quickly it circulates around their body. Genes also determine the synthesis of testosterone receptors, and how many and how sensitive such receptors are. The gene called monoamine oxidase A (MAOA) produces an enzyme which regulates the metabolism of serotonin in the brain. Aggressiveness is influenced by a variation in the MAOA gene; Low level activity of MAOA results in low levels of serotonin which have been associated with increased risk of aggression but the high MAOA variation is not. A strength of this explanation is that it
