    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 nucleus of a somatic cell, or any body cell. This technique is called Somatic Cell Nuclear Transfer, or SCNT. Then, scientists use electricity or a source of stimuli to help the newly formed embryonic cell start its dividing process. After allowing the…

    1938 by Hans Spemann, called “fantastic experiment” (The Embryo Project Encyclopedia). He performed this cloning on a molecular level. He took one nucleus from one egg cell and replaced it with another nucleus from another cell; he hoped to grow an embryo. He discovered these embryotic cells could self-regulate to varying degrees. The experiment was ruled successful because the cell split into two-heads and 1 tail. These discoveries made the avenue for further cloning discoveries, and much more…

    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…

    Cloning: Benefits, Harms, and Misconceptions For decades scientists have pondered over the idea of somatic cell nuclear transfer, otherwise known as cloning. In 1996, their ideas became tangible with the creation of Dolly the sheep, the first organism to ever be conceived through nuclear cell transfer. Today, scientists are closer than ever to clone human cells successfully. Although there is excitement over this potential scientific breakthrough, there are fearful and apprehensive reactions as…

    1998, p. 239). It is after all that the cloning of sustainable human embryos for stem cell therapy may perhaps be a conceivable reality to imagine in healing or preventing all sorts of diseases to transplantation of much-needed organs. For instance, somatic…

    the Finn Dorset ewe from which scientists took cells (Aldridge). While it’d be of interest to jump the gun to one of the biggest steps in genetics, cloning could draw its history all the way back to 1885 and is even a basis of the critically acclaimed novel by Aldous Huxley, Brave New World. Although a great number of people think of cloning as…

    through identical twins. Clones can also be created in a laboratory (What is Cloning?). In a laboratory, clones can either be created using a process called Artificial Embryo Twinning or Somatic Cell Nuclear Transfer. Artificial Embryo Twinning is a cheap way to create clones like they occur in nature. Scientists take a very early embryo and separate it into individual cells; the scientists then allow these cells to divide for a small amount of time. These embryos are then placed into a…

    scientists were able to clone mice. By the end of the year 2000, thousands of animals were successfully cloned. In 2001, a human embryo was cloned successfully to a 32 cell stage, before scientists terminated it. Had this experiment continued, a child might have been born with identical DNA to it’s parent. We are capable of cloning, the technology is there, but whether we should exercise this technique on humans or not is an ethical question that has haunted progressive thinkers…

    with an optic nerve transplant, that day could be today using therapeutic cloning. Cloning for therapeutic purposes (also called research cloning and somatic cell nuclear transfer (SCNT) is a type of cloning with the goal of harvesting embryonic stem cells to grow tissues and other biological products with therapeutic value (Nicholson 2001). According to the article “How to Make a Stem Cell”, an embryo, by day five, contains 250-300 cells, including stem cells that eventually transform into…

    Cloning is nothing new. Organisms are considered clones when their entire DNA is identical. Clones are able to happen naturally as is the example of biological twins or they can be made in a lab through modern technologies. The three types of cloning that currently exist are: reproductive cloning, gene cloning, and therapeutic cloning. Cloning an organism is different from cloning a gene. The process of cloning an organism involves making an exact genetic copy of the whole thing rather than…
