Cloning
Introduction
Today’s technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is a process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell. Different from the common propagate, cloning need only one cell and without sex. In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell had been taken from the udder of adult sheep, which show the first cloning experiment was successful.
The history of cloning
About the cloning history, we trace back to 400 million years BC, the plants could clone themselves but not to long. The human found the cloning 200 years ago, the first person who did the cloning experiment is a German biologist named Han Spermann, he uses the egg white to clone chicken in 1938 but it was failed. Until 1981, Kal Illmensee and Peter Hoppe report that they clone normal mice and embryo cell; it was a huge progress of the cloning history. After 2 years, the embryologists in UAS first cloned the human’s cells; they put 32 cells into a surrogate mother, and then have cloned 4 extra same cells. In 1997, Ian Wilmut and his colleague Keith Campbell cloned a new adult sheep called Dolly. (Will, April 2002) So human spends long time on cloning research.
The process of cloning
The cloning has two main parts, one is the plant cloning and the other is the animal cloning. One type of plant cloning naturally occurs when a plant grows a runner. The runner grows horizontally across the ground forming a carbon copy of that same plant at the end. Eventually the runner dies and the daughter plant is separated from the mother plant. Another is when you cut a branch or leaf off of a plant and plant it. It will grow another identical plant. That method is called a cutting. Such as stolon, it is a weak branch of a plant, when it falls over and the tip touches the ground. The tip swells and roots are formed so that growth in the plant can continue.
The other kind of cloning in animals is nuclear transfer cloning. Nuclear transfer is when the nucleus of one cell is implanted into another cell that has had the nucleus taken out.
As a child, Ishmael Beah seemed like he was playful, curious, and adventurous. He had a family that loved him, and he had friends that supported him. Before the war, Ishmael had a childhood that was similar to most of the children in the United States. Unfortunately, the love and support Ishmael grew accustom to quickly vanished. His childhood and his innocence abruptly ended when he was forced to grow up due to the Sierra Leone Civil War. In 1991, Ishmael thought about survival rather than trivial things. Where was he going to go? What was he going to eat? Was he going to make it out of the war alive? The former questions were the thoughts that occupied Ishmaels mind. Despite his efforts, Ishmael became an unwilling participant in the war. At the age of thirteen, he became a
Ishmael was a normal 12 year old boy in a small village in Sierra Leone when his life took a dramatic turn and he was forced into a war. War has very serious side effects for all involved and definitely affected the way Ishmael views the world today. He endured and saw stuff that most people will never see in a lifetime let alone as a young child. Ishmael was shaped between the forced use of drugs, the long road to recovery and the loss of innocence of his
Ishmael starts his journey with a will to escape and survive the civil war of Sierra Leone in order to reunite with his mom, dad, and younger siblings, who fled their home when his village was attacked by rebels. Having only his older brother, who he escaped with, and a few friends by his side Ishmael is scared, but hopeful. When the brothers are captured by rebels, Ishmael’s belief in survival is small, as indicated by his fallible survival tactics when he “could hear the gunshots coming closer…[and] began to crawl farther into the bushes” (Beah 35). Ishmael wants to survive, but has little faith that he can. He is attempting to survive by hiding wherever he can- even where the rebels can easily find him. After escaping, Ishmael runs into a villager from his home tells him news on the whereabouts of his family. His optimism is high when the villager, Gasemu, tells Ishmael, “Your parents and brothers wil...
The first story Ishmael tells is that of the takers. Every story is based on a premise. The taker premise is that the world was made for man. If the world is made for man, then it belongs to him, and man can do what ever he pleases with it. It's our environment, our seas, our solar system, etc. The world is a support system for man. It is only a machine designed to produce and sustain human life.
In language of the sort one might expect from a well educated man speaking with a friend, Ishmael told Quinn the story of his life. A large portion of it was spent in captivity, before a wealthy elderly man befriended and educated him. At the end of Ishmael's tale, Quinn was still somewhat befuddled.
This is at core a pitiful story which encompasses of ruthlessness and miseries endured by Ishmael Beah. All the trials in this story are chronologically prescribed and heart sobbing, in which a person who reads can in time weep while interpreting.
To go along with my look at the film today, I will also explain a bit about Ishmael as well. I wrote the book the in 1992 and it has been called a philosophical novel for the themes and questions that I put into the story. It examines mythology, its effects on the ethics of others, and how that can relate to the sustainability of the environment. In the novel I use the style of a Socratic dialogue in order to deconstruct the notion that humans are the pinnacle of biological evolution. I break down that perception in the book in order to create a more realistic interpretation of who humans are and what they represent to the earth.
3) During the late 1800s, the United States reasserted the Monroe doctrine and promoted Pan-American interests. By supporting Cuban independence from Spain, participating in the Inter-American Conference, making reciprocity provisions in the McKinley Tariff Act, and being involved in the Venezuela-British Guiana border dispute, the U.S. showed a this change in foreign policy. Prior to this period, America had been isolationist, concentrating on domestic issues and nation building. America was now going to be an active player in anything that happened in the Western Hemisphere. Security and economic interests were going to be protected and American influence was going to be spread.
The book is based on actual events and is expressed through a personal point of view. Ishmael wrote a memoir that tells the story of a young boy who is torn from his peaceful life, and then forced into a frightening world of drugs and slavery. In writing about his experiences, he has made the decision to present his experiences in a particular way by missing out details and recounting others. This along with the language used and the order, in which the events are disclosed, all serve to create a particular interpretation and to guide the reader to respond in a particular way.
Ishmael ends up making new friends by being on the debating team. Sitting in the debating team and speaking builds his confidence. Gradually as his confidence increases, Ishmael is able to face his fears and speak in front of an audience. At the end of the school year, Ishmael finally had the courage to talk in front of the whole school at assembly. He was asked to write a poem and he did not hesitate. James Scobie has changed Ishmael’s whole personality putting him on the debating team. He has built confidence, which completely changes
At first, he is angry, as it reminds him of the counterculture movement of the 1960s, which he participated in only to discover that there was no easy way to save the world.
Cloning is a process by which genetically equal organisms are created with the same DNA. In simplest terms, clones are like twins born at different times. This procedure poses various dangers to society and humankind. One of the greatest threats this procedure creates is among

Recent discoveries involving cloning have sparked ideas of cloning an entire human body (ProQuest Staff). Cloning is “the production of an organism with genetic material identical to that of another organism” (Seidel). Therapeutic cloning is used to repair the body when something isn’t working right, and it involves the production of new cells from a somatic cell (Aldridge). Reproductive cloning involves letting a created embryo develop without interference (Aldridge). Stem cells, if isolated, will continue to divide infinitely (Belval 6). Thoughts of cloning date back to the beginning of the twentieth century (ProQuest Staff). In 1938, a man decided that something more complex than a salamander should be cloned (ProQuest Staff). A sheep named Dolly was cloned from an udder cell in 1997, and this proved that human cloning may be possible (Aldridge). In 1998, two separate organizations decl...
Cloning is asexual reproduction. Cuttings are taken from a mother plant in vegatative growth, and rooted in hydroponic medium to be grown as a separate plant. The offspring will be plants that are identical to the parent plant.
