Reproductive Cloning With constant new developments in science, society is forced to react and adapt. Along with these new developments, citizens are left questioning the ethics behind the experiment. Almost one hundred thirty years ago, society was introduced to the idea of cloning. It was not until the year nineteen ninety-six when the idea became reality and the first cloned mammal was born, Dolly the sheep. She set the grounds for the next cloned mammals to come. The process of cloning is a…

observations a 9:3:3:1 ratio of phenotypic traits in the second filial generation. Thus he formulated the law of independent assortment which will be examined in this experiment. This law states that alleles for different genes separate independently during gamete formation (Reece et al., 2011). The Drosophila Melanogaster is the organism used to study Mendel’s proposed patterns of inheritance because of its obvious advantages in that it is small and easy to contain and breed in a laboratory;…

Mitosis is a process of cellular division. What happens though when Mitosis (process of cellular division) goes wrong? You can get a disease from Mitosis going wrong, some very bad ones too. A widely known disease caused by cellular division going wrong is Cancer and Tumors. (1)Disrupted passage through mitosis often leads to chromosome missegregation and the production of aneuploidy progeny. Aneuploidy has long been seen as a frequent characteristic of cancer cells. Also Aneuploidy has been…

Charles Darwin, associated with Cambridge University, revolutionized science with his theories of evolution. His ideas birthed new ways of understanding how species came to be. According to Darwin , the key driving force behind evolution is natural selection, which occurs under environmental pressures leading to speciation or changes within species. It favours the traits most adept to surviving in an environment’s conditions and weeds out those that are not through the four aspects of natural…

Covered with Black and White a fur coat, the giant pandas are bear like in shape. The adult pandas have an approximate length of six feet and can weigh up to two hundred eighty pounds. Male pandas can be about the same size as a American Black Bear, with the exception that they cannot stand upright or hibernate. The giant panda exhibits bilateral symmetry with its large head, plantigrade feet, heavy body, rounded ears, and their five inch tails. The panda has adapted to consuming bamboo by using…

In all the years that have past there is only ever been a few theories of evolution; evolution is how different organisms have developed or diversified from earlier ancestors in the history of the earth and is also known as the diversity of life. Evolution usually occurs very slowly, over long, extensive amounts of time. The idea of evolution can go as far back as the middle ages, because Aristotle explained all natural things are flawed and can be fixed in a natural way such as changing forms,…

State babies are made in labs. “These,” he waved his hand, “are the incubators.” And opening an insulated door, he showed them racks upon racks of numbered test-tubes. “The week’s supply of ova. Kept,” he explained, “at blood heat; whereas the male gametes,” and here he opened another door, “they have to be kept at thirty- five instead of thirty-seven. Full blood heat sterilizes.”(pg 5) This proves that embryos are created in labs. The embryos are made by machines and then kept in…

In the middle of the menstrual cycle, the women’s ovaries release an egg. The ovaries produce and release female gametes and sex hormones. In the ovaries, the ovarian follicles are tiny sac like structures that hold a single primary oocyte (Primal Pictures). Every day, a bunch of follicles will begin a process of maturation but eventually only one follicle will end…

1.1 The structure of DNA Deoxyribonucleic acid (DNA) is often referred to as “the molecule of life”. It encodes the instructions that are used in the development and functioning of all known living organisms. The molecule itself was first discovered in 1860 by Friedrich Miescher (reviewed in Dahm 2005). Further work was performed by other chemists, including Phoebus Levene who identified the components of the molecule, including the presence of ribose sugars and phosphate groups, as well as four…

The Immorality of Abortion In 1973, throughout Roe v. Wade case, the Supreme Court decided that a woman's choice of abortion was legally more logical than that of the child inside of the womb. Since then many new medical and scientific improvements have been made which would pose as a threat to this argument. F. M. Kamm in her novel Creation and Abortion says it this way, “Legislation was lax then, and so the theory is that those who proposed the fourteenth amendment, citizens of their times,…
