Scientists have been successful in the areas of cloning before, but a breakthrough in 2013 is helping the area of stem cell usage. There is much controversy over the use of stem cells, but this new technology may help lessen that. Using a technique called “somatic cell nuclear transfer,” researchers cloned a human embryo. Within an embryo are embryonic stem cells, which are unique because of their never-ending list of uses. Stem cells are a crucial part of many new medical research projects because they can be manipulated into producing any type of bodily cell, including more stem cells.
Katia Vergara English Honors, Period 1 Cloning is a crucial advancement in life, not only to the modern world, but also reaching far ahead into many future generations to come. Scientists believe it is the key to finding remedies for hard-to-cure diseases. Cloning is not one, but two differentiated procedures, one being the way of creating wide-ranging medicine and the other creating two identical babies. Taking into consideration how prominent biotechnology has become in recent years, cloning I my crucial analysis of the subject seems to bring the farthest advances and potential. Cloning can be helpful to those who.
One of the most controversial topics in the field of biomedicine has been the research of embryonic stem cells. Stem cells are extremely fascinating to what they can do they have the potential to develop into many different cell types in the body during early life and growth. In many tissues they serve as a sort of internal repair system, dividing without limit to replace other cells as along as the person is still alive. When stem cells divide they could become specialized cells such as muscle cells, red blood cells, brain cells, and etc. their unique generative abilities, stem cells offer a new potential for treating diseases such as diabetes, and heart disease.
“For a fertilized egg, there is no consciousness and also no history of consciousness” (Stem). If abortions are allowed within the United States, why shouldn’t embryonic stem cell research be? Another claim against embryonic stem cell research is that it devalues human lives. “Some argue that researching embryonic stem cells will lead us into cloning technology” (Embryonic). While embryonic cloning is a possibility, we already possess the capabilities to clone so cloning is an invalid argument.
They utilize their ability to differentiate to the fullest extent, particularly to repair damaged body tissue or create new cells. Two types of stem cells used, include embryonic and adult. Both hold great features, but only embryonic cells have the capability of fully repairing tissue, and becoming any cell. Whereas Adult Cells may not have as much flexibility differentiating, and become limited on their transforming abilities. The detection of stem cell research prevails as a wonderful discovery that has had a large effect on today’s medicine.
Genetic engineering has been one of the most controversial ethical issues since 1997; when Dolly, the first successfully cloned sheep, was announced. Dolly has redefined the meaning of “identical twin”; not only does she look exactly like her mother she also has the same genetic make up. This experiment was not only impossible but unthinkable. Yet, Dr. Ian Wilmut revealed Dolly on February 23, 1997, at seven months old ( Travis 1). On the surface genetic engineering may appear to be the solution to all of society’s ills and the worlds problems.
However, as previous experiments had shown, the artificial zygotes created we... ... middle of paper ... ...d have a greater probability of becoming pregnant. Furthermore, the fertilized zygotes could be stored for future use. Therefore, if a child was placed in a situation where he needed bone marrow to survive, an identical twin could be created in order to supply its extra bone marrow (Robinson 2001). Through further research on cloning, scientists will be able to gain a greater understanding of human genetics and biological processes and can also use the technology for various medical purposes. With continued work on human embryo cloning, organs and bone marrow will be harvested for humans in dire need.
Cloning – Well, Split My Embryo! Genetic engineering, altering the inherited characteristics of an organism in a predetermined way, by introducing into it a piece of the genetic material of another organism. Genetic engineering offers the hope of cures for many inherited diseases, once the problem of low efficiencies of effective transfer of genetic material is overcome. Another development has been the refinement of the technique called cloning, which produces large numbers of genetically identical individuals by transplanting whole cell nuclei. With other techniques scientists can isolate sections of DNA representing single genes, determine their nucleotide sequences, and reproduce them in the laboratory.
Changes to existing genes (mutations) result in variation. Natural selection acts on this variation and preserves the best. So while the variation may be random, the process of microevolution is not. Natural... ... middle of paper ... ...ific experiments can not test macroevolution, there is no direct evidence to suggest that the processes behind microevolution can also bring about the evolution of new structures or genes. In other words, microevolution should not be extended to support macroevolution.
Is it ethical to kill a being classified in biological terms as a life form for the potential advancement of science? Is an embryo even worthy of rights if it can’t think, feel, or communicate? Or do the positives of embryonic stem cell research so far outweigh the negatives that the sacrifice is minimal? Adversaries of embryonic research explain that it is absolutely unethical, while supporters argue that this research is essential to our medical future. There may never be one right answer.
