Nuclear transfer

On July 5, 1996, a sheep named Dolly, was successfully cloned using somatic cell nuclear transfer. What does this have to do with cloning human body parts? Well it may be that humans and animals are both mammals, but it is actually how it is cloned. Somatic cell nuclear transfer (SCNT) to be exact. It may sound like a great idea, but many people have moral issues with it. Some reasons why others would like it are, it is safer and easier than transplants, it could help cure diseases, shows other countries how advanced America’s technology is, it can help save lives, by cloning stem cells and finally there may not always enough body parts. The cloning of human body parts should be…

Stem cell research is a global topic within the science community. There have been numerous discoveries in this field worldwide, and these findings have many scientists jubilant about the possible future implications. Most of the research is associated with the topic of cloning. In the scientific community, the term cloning is broken down into two categories: Therapeutic and Reproductive. In Therapeutic Cloning, the nucleus of an unfertilized egg is removed and replaced via injection with the…

We've all heard the popular phrase “just because you can doesn't mean you should,” and most people understand what this concept means; don't play god (I;I). A simple concept that I agree with, but many scientists like Victor Frankenstein and Luigi Galvani disregard this warning for the sake of progress. From my viewpoint, I think the answer is simple; if it defies the laws of nature than maybe it shouldn't be done. (I;I) Let me begin by pointing out the most obvious example of playing…

In 1996 Dolly the sheep was born. However, she was not born like most other sheep. Instead, Dolly was cloned from the DNA of an adult sheep. Although Dolly seemed healthy, she died in 2003 after being diagnosed with a progressive lung disease. Dolly was the only sheep out of 277 attempts that made it to a live birth. Would it be safe to take that chance when experimenting with cloning human babies? Some people seem to believe so, and agree with the idea of cloning to have a child. These people…

The process of somatic cell nuclear transfer SCNT is a laboratory procedure where the purpose is to copy, reproduce, a live creature or CLONE it. The nucleus of a somatic cell, any cell of a living organism other than the reproductive cell, the cytoplasmic factors influence the nucleus to turn into a zygote. As a result, the egg undergoes a blastocystic stage and it creates the embryonic stem cells. The process takes two cells, one is the donor of the nucleus and the second the receiver of this…

Somewhere within a lab, Ian Wilmut lead a team of scientists to create the world’s first animal from a somatic cell. And from that revolutionary discovery, scientists use this way to artificially produce living creatures that even today are being used. Dolly the sheep died many years ago and many have wondered about the ethics of cloning an animal, whether or not Dolly’s “sister clones” were actually genetic matches and whether cloning is a bad way of producing a living creature and shouldn’t be…

experiment created a tadpole, but due to the advanced embryos the tadpole grew abnormally and died. This experiment was very important and very impactful for the future. Scientists realized that nuclear transfer was a viable cloning technique. A few years later, in 1958, John Gurdon cloned a frog by nuclear transfer from a differentiated cell (Sir John B. Gurdon-Facts). Despite previous failures, he created tadpoles that were genetically identical to one another. Importantly, this experiment…

Somatic cell nuclear transfer is taking the nucleus from the cell of a mature animal and inserting it into an embryo, very different from and much more difficult than regular nucleus transfer. The struggle with this type of transfer is that adult genes have already differentiated and “shut down” unlike embryonic cells and in order to complete the transfer scientists must reset these cells to their embryonic state. A considerable amount of times this process is incomplete, causing the embryo to…

This publication declares in working towards stem cell research by way of using early and preliminary studies on human somatic cell nuclear transfer in cell division as well as parthenogenesis or activation of an unfertilized sperm cell making a preimplantation embryo grow into replacement tissue because: human embryonic stem (ES) cells, and other cells derived from the inner cell mass of the preimplantation embryo are totipotent, that is, they are capable of forming any cell or tissue in the…

Cloning is the process of creating a new organism that is genetically identical to a single common ancestor. Genetic information from a single parent organism is copied. Cloning is done by nuclear transfer, which is when the nucleus of an egg is removed and replaced with a nucleus from a donor cell. Energy is created in order to jumpstart the cells to start dividing. There are two types of cloning: Therapeutic cloning and Reproductive cloning. Therapeutic cloning is when the cloned cells are…
