Genetics

natural selection, genetic drift, and gene flow. Mutations are the only force that can change the genetic code and without them the other forces wouldn’t happen. When a mutation takes place in a sex cell, it can them be passed down through generations. Natural selection was first brought about by Charles Darwin. It is the belief that the better an organism adapts to their environment, the more likely they are to live longer as well as reproduce. Genetic flow is the spreading of genetic material…

process of altering an existing gene in the DNA and inserting it into cells in an organism to fix genetic disorders or diseases. In humans, gene therapy is the process in which some of the defect cells or the cells carrying the disease are removed from the body (eg. lung cells in a Cystic Fibrosis patient) in order to harvest their DNA. The base sequence of their DNA is then altered to remove the genetic disorder by deconstructing and reconstructing DNA through techniques such as PCR, ligation…

example of epigenetics. Allowing them to have a better understand of genetic remodeling. After stating his research, Hayak says "lifestyles and diet of parents can have vital effect on their children and grandchildren... but they also raise the probability that improving your lifestyle could give your genes the best possible chance of being expressed in a healthy way after they are passed on." this lets the reader know that genetic remodeling can happen and creates logos by having the author…

only spark an extended array of ethical concerns but could also backfire in several ways. Human genetics has been the topic of several debates for an extended period of time, specially during times of tragedy in history. There is a belief that some individuals are genetically superior than others thus making their genetic material desirable. During the twentieth century, the idea of modifying genetic information to “improve”…

The debate on the extent of the effects of nature versus nurture has existed for centuries. Nature describes human genetics and heritable traits, and nurture expresses how humans are raised and their surrounding environment. Many psychology scholars disagree over the comparative contributions of genetics and experience. Plato alleged that both personality and intelligence level were hereditary, while Aristotle asserted that human’s knowledge and traits came completely from experience (Myers…

Figure 1: Shows the gene expression changes found in Arabidopsis after the insertion of the IRX1, IRX3, and IRX5 mutants(Brown). 1A shows the principal component data collected from the targeted areas of the plant(Brown). 1B shows a comparison of gene expression of the base and tip of the stem and the change of level(Brown). 1C shows the slope of genes most likely to be related to IRX3(Brown). From Figure 1B, it is shown through analysis that there are several hundred genes that show an increase…

They would then compare the results with the humans once they were used as test subjects. Animals have proven to be a source for testing since they have similar genetics and organ functions; however they have also proven to be difficult subjects for testing since they have different replications of disease and reactions. Animals’ genetic material is similar to the humans. Scientists are now beginning to use…

The case study is based on the genetic disorder and the confidentiality of patient .The main motive of disclosing a genetic disorder is to tell other family members about the risk of the diseases but, this is not a simple task. Patient's consent is also an important thing to consider; in this case Peter, who is suffering from genetic disorder, does not wants his doctor to reveal his disorder and other risks to his close family members such as his brothers, niece and nephews.His brothers have a…

Researchers and scientists have now opened a new page in genetics called genetic engineering. With this new technology it has become possible to bypass the laws of nature that seem impossible to bypass. Evolution for instance, natures train tracks, you can’t get off of them without a catastrophe happening, or can you? Actually, scientist and researchers alike believe they can. How you ask? Genetically modified organisms, or GMOs. The odd thing about these GMOs is they are usually thought of as…

Is the way people are born like the Genetics of a child. Studies show that twins can look alike and others may be twins but not look alike at all and one twin can be mental and the other may have a 50% chance of developing conditions like bipolar and major depression. Example: Twins sisters that laugh and look the same because they are twins. But raised in different towns and aren't the same height. They can also read eachothers minds and Nature is the way you may act and like nurture is on…
