Lecture 7 Questions 1. Explain in your own words where genetic differences observed among people come from and how they give rise to variation in traits within the human population. Genetic differences among people are fundamentally caused by differences in the DNA sequences between people. Differences in DNA will lead to different alleles of genes and code different proteins, ultimately expressing different traits. The primary source of genetic variation for all organisms is mutation, a change in
and nurture. Because monozygotic twins originate from one fertilized zygote that split into two, they share identical genetic information. Any difference in phenotypes between monozygotic twins would therefore most likely result from environmental factors. Dizygotic, or non-identical twins are useful controls in studies involving twins. While they only share about 50% of their genetic information, as they are no more related than any other siblings, they shared a womb. Therefore, they can show if the
Muscular dystrophy ,MD, is a group of inherited diseases associated with excessive weakness in muscles.1 MD causes disability in movement due to genetic disorder that results defects in the muscle protein, and the defects can lead to the death of muscle cells and tissues.1 Some of the genes that are responsible for the disease have been identified, but some have not.1 Although MD has various types that have different symptoms, the main symptom in all types is the weakness of muscles.1 In some types
raise and call their own. Sometimes this dream comes true, but with a cost. A child can develop any number of deathly diseases and illnesses and there is nothing we can do about it… Until now. The technology has been developed for preimplantation genetic diagnosis (PGD) to be able to create saviour siblings in order to save an existing child’s life. Some believe this is the wrong thing to do ethically, and they feel sympathy for the saviour sibling for they believe he or she will not be treated equally
In “The Case Against Perfection”, Michael Sandel argues against the subject on enhancement being wrong. Sandel believes that we have to accept the fact of who we are when it comes to the physical aspects we obtained naturally from birth. In this essay, I will be siding with Sandel’s argument, as is unnecessary to enhance ourselves due to the fact that many of our characteristics that we gained from birth are beyond our control. Michael Sandel believes that enhancement gives an unfair advantage to
he last movie we watched Gattaca, suggests that a genetic predisposition of a person determines a person’s identity. In the movie, Vincent was born without any technology, but the technology predicts that he is going to live for 30 years. Similarly, his brother Anton was genetically predetermined which makes him superior . We see Anton beats Vincent everytime they compete in swimming which shows that genetically predisposition makes a person strong, competitive, and powerful. Genetically predetermined
Abstract Prior to conception, designer babies, or genetically engineered/modified babies, are created through pre-implantation genetic diagnosis, (PDG) in order to prevent genetic diseases and inherited medical conditions; however, this procedure is expensive, prejudice between “Designer” and “non-designer” children will arise and if the process is not done carefully, the embryo could be terminated. This paper will express to the readers that designing babies due to disease is ethical yet altering
been told around animals and plants and cells, which consequently made me to study natural science in high school. Combination of my intrinsic tendency to endless journeys and discovery of the pioneer role of cellular and molecular researches and genetic studies in the future of medicine and their potential power of making science fictions become true – as it is not far beyond the reality by CRISPR gene editing technology and human genome project WRITE – , made me to choose cellular and molecular
Soybean is an important crop, with food, nutritional, industrial, and pharmaceutical uses. Soybean seeds contain about 40% protein and about 20% oil. They are also abundant in physiologically active metabolites such as isoflavones, lecithins, tocopherols and saponins, in addition to functional proteins and are used as an affordable source of foods that promote and maintain health (Sugano 2005). The genomic era is now under way for soybean, as for other many crops. Recently, a soybean genomics database
These cells could then be used for medical purposes, possibly even for growing whole organs. The stem cells cloned from someone with a disease could help researchers understand the disease and develop treatments (learn genetics). Even though, cloning can save lives in the future the topic is still very controversial. It raises a number of ethical, legal, and that need to be taking in consideration. Many organizations believe, using animals for cloning experiments is an
