Persuasive Essay On Human Cloning

In recent years, science and technology have advanced beyond any previous expectation and will continue to grow faster than we could imagine. One aspect of science that is making great advances is cloning. Cloning has been around for over one hundred years despite people believing it started with Dolly the sheep in the 1960’s. While the advances in cloning are fascinating, converting over to human cloning brings in some ethical issues that need to be addressed. The ethical dilemma that comes from cloning would be, “Is it right to be able to play God and create life?” Human cloning is ethically a major issue in reference to human rights infringement as research tools, unrealistic expectations to be the same as the originals causing physiological

He found that the cell nucleus controls embryonic development. He used the same process as before by using a strand of baby hair and tying a noose around the cell. When he did it this time he just temporarily tightened the fertilized salamander egg to push the nucleus to one side of the cytoplasm. The eggs continued its cell divisions but only on the one side with the nucleus. He waited for the nucleus side to divide four times, creating sixteen cells, and then he loosened the noose allowing it to transfer back over to the non dividing side of the egg. After, he tightened the noose again and separated this cell from the rest of the cluster that made up the embryo. The cluster continued to grow into a salamander and as did the single cell. What is significant about this experiment is that this was the first instance of a nuclear transfer. It also showed that the nucleus from an early embryonic cell directs the complete growth of a salamander, effectively substituting for the nucleus in a fertilized egg. What that does is it proves that you can remove a nucleus, and then replace it and the cell will grow. This was a great scientific

This continued Spemann’s research while his was simply displacing the nucleus and Briggs and King’s experiment actually removed the nucleus from the embryo and moved it into an enucleated frog egg. An enucleated frog egg is an egg that had the nucleus removed. The emerging cell grew into a tadpole.

One occurrence that was denoted through the research was that nucleus’ that were taken from from more advanced embryos tended to be less successful at growing. Of those nuclei that beat the odds, they tended to grow abnormally. The findings in this experiment found that nuclear transfer was a viable option when it came to cloning. This reinforced the previous two findings. With the nucleus directing the cell’s growth and the organism’s development being the first. Secondly, cloning cells at later stages is less effective than cloning embryonic cells at the earlier
