Cloning is a DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques. This means to reproduce or propagate asexually and some sexually. Cloning is made when you have several embryos and you try to duplicate them to produce more eggs which is called SCNT. SCNT (Somatic Cell Nuclear Transfer) is used so that they can take a piece of DNA from an egg and transfer it to another egg after the nucleus has been eliminated by an ultra violet beam. This technique is really hard to accomplish but can be done by well experienced scientists. There are many reasons why scientist would like to clone, and two of the main reasons are finding a cure to certain types of diseases and helping the endangered species come back to life like they once were.

Different Types of Cloning

When we speak of cloning, we typically think of organism cloning, but there are actually three different types of cloning. Molecular, Organism, and Therapeutic cloning. The first one is Molecular cloning, this focuses on when a DNA from an organism is transferred to a self-replicating genetic element such as a bacterial plasmid. In other words, a small piece of the DNA strand is removed and united with a plasmid which reproduces itself to create multiple copies of the same DNA code. This type of cloning is also called gene cloning. The second one is Organism cloning, and this involves making an identical copy of an entire organism and a good example would be Dolly the sheep. This type of cloning is also called reproductive cloning. The last one is Therapeutic cloning. This involves the cloning of human embryos for the production of stem cells. The purpose of therapeutic cloning is to extract the stem ...

... dolly the sheep was a success because they could see that Dolly’s face was clearly a whiteface poll Dorset and not a Scottish blackface. She was cloned at the Roslin Institute in Scotland and lived there from her birth in 1996 until her death in 2003 when she was six. She was born on July 5, 1996 but not announced to the world until February 22, 1997. Her stuffed remains were placed at Edinburgh's Royal Museum, part of the National Museums of Scotland. Ever since Dolly the sheep, there has been so many other mammals cloned like frogs, which are said to be the easiest to clone.

    Understanding the facts as well as procedures between the many different types of cloning is very crucial. When everything boils down there are three types of cloning known as DNA cloning, therapeutic cloning and reproductive cloning. DNA cloning is the copying of a gene in order to transfer it into another organism which is usually used by farmers in most of their crops. Therapeutic cloning is the use of stem cells used to help take the place of whatever cell is missing which is potentially used to help the ill. Stem cells contain the potential to grow and help replace the genes that are missing in order to fix whatever is genetically wrong with your body or any genes that you may be missing. Reproductive cloning actually produces a living animal from only one parent. The endless possibilities and perhaps hidden motives of using genetic engineering are what divide as well as destroy the scientific community’s hope for passing laws that are towards pro cloning. Many people within soci...

  • Can Cloning and Christianity Coexist

    Cloning, upon first hearing the word cloning, the thought of Dolly the sheep pops into the mind. The first and most used type of cloning though is not the type that creates animals, but rather DNA cloning. “Cloning is an umbrella term that science uses to indicate the duplication of biological material.”(Human Genome Project) Cloning is further broken down into three categories. The first is DNA cloning, which is the replication of DNA strands. DNA cloning is usually the process of getting a cell to replicate a desired gene for us. DNA cloning has been used since the 1970’s and has persisted as an effective cheap means of replicating DNA of interest in a foreign host cell. “To "clone a gene," a DNA fragment containing the gene of interest is isolated from chromosomal DNA using restriction enzymes and then united with a plasmid that has been cut with the same restriction enzymes.”(Human Genome Project) Plasmids are not part of the chromosome but they replicate along with the cell when it replicates and divides. Since they are not a part of the chromosome they are easier to isolate and manipulate without affecting the cells function. “When the f...

  • The Pros And Cons Of Cloning

    860 Words  | 2 Pages

    Cloning has been in nature for thousands of years, a clone is a living thing made from another consisting of the same DNA. For example identical twins are clones because they have the same DNA but the differ because the twins begin after conception when a zygote, a totipotent stem cell, divides into two, some plants self-pollinate and produce a seed, which in turn, makes plants with the same genetic code (Hyde). According to the Human Genome Project there are three types of cloning, DNA, therapeutic and reproductive; DNA cloning involves transferring DNA from a donor to another organism, therapeutic cloning, known as embryo cloning, involves harvesting stem cells from human embryos to grow new organs for transplant, and last is reproductive cloning which creates a copy of the host (Conger). One of the earliest cloned animals was a sea urchin by Hans Dreisch in the late 1800’s. Unlike Victor Frankenstein, Dreisch’s goal was to prove that genetic material is not lost in cell division, not to create another being, (History of Cloning) stated by Frankenstein “that I might infuse a spark of being into the lifeless thing that lay at my feet.” There are many ways an animal...

  • Is Cloning Ethical or Unethical?

    911 Words  | 2 Pages

    Cloning is the creation of an organism that is an exact genetic copy of another. Every single bit of DNA is the same. There are three different types of cloning. Gene cloning produces copies of genes or fragments of DNA, reproductive cloning creates copies of whole animals, and therapeutic cloning builds embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues. In 1997 scientists in Scotland announced the birth of a clone. Its name was Dolly; after the American country singer. She was the clone of an adult female sheep, and the first mammal to ever be cloned successfully. As Dolly matured, she mated with a ram, and gave birth to a lamb showing that clones have the ability to reproduce. Dolly died at the age of six. According to Sheep 101, the life expectancy for a sheep is 10-12 years, but some sheep can live up to 20 years.

    This is explained by Craig Freudenrich. He discusses this on the website HowStuffWorks. Freudenrich tells of how Ian Wilmut and his colleagues successfully cloned Dolly the sheep at the Roslin Institute in Midlothian, Scotland. Dolly the sheep was the world's first successfully cloned mammal, cloned from an adult somatic cell. He writes how after Dolly, scientist have been cloning animals like cows and mice. “They rely on transplanting the genetic information from a specialized cell into an unfertilized egg cell, whose genetic information has been destroyed or physically removed.” (How Cloning Works) This information is very enlightening to anyone who questions how cloning works. Furthermore it secures the information needed to inform the general public of what they need to know to have a responsible and appropriate

    First, what exactly is cloning? In biology, cloning is used in two contexts: cloning a gene, or cloning an organism. Cloning is the reproduction of a human or animal whose genetic substance is identical to an existing being, such as an embryo or fetus. This is reproductive. Cloning a gene means to extract a gene from one organism and insert it into a second organism. Cloning an organism means to create a new organism with the same genetic information as an existing one. This is therapeutic.

    Gene cloning is used to create a large number of copies of a gene. The cloned DNA can be used to decipher the function of the gene, investigate a gene’s characteristics like size, or expression, look at how mutations may affect a gene’s function or make large concentrations of the protein coded for by the gene. Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It creates an exact genetic copy, or clone, of an individual. It is accomplished using a process called somatic cell nuclear transfer (SCNT)....

  • The Science of Cloning

    843 Words  | 2 Pages

    In the essay, Cloning Reality: Brave New World by Wesley J. Smith, a skewed view of the effects of cloning is presented. Wesley feels that cloning will end the perception of human life as sacred and ruin the great diversity that exists today. He feels that cloning may in fact, end human society as we know it, and create a horrible place where humans are simply a resource. I disagree with Wesley because I think that the positive effects of controlled human cloning can greatly improve the quality of life for humans today, and that these benefits far outweigh the potential drawbacks that could occur if cloning was misused.

    Imagine being a first year medical surgeon just out of the highest-ranking university in the nation. You are placed in the ER, in the Methodist Hospital building, as your days are spent saving people from the cruel realities that they are forced to live among. Day after day, you see handfuls of people coming in with a variety of gunshot, knife, and domestic violence wounds. Your troubles are easily compensated, however, by receiving over $200,000 a year, a brand new Mercedes, and a house upon the palisade shores. Suppose for a moment that one evening while you are on duty, an ambulance radios in and informs the hospital staff that they are bringing in a multiple gunshot wound victim and to prepare the ER for an immediate operation. You begin to order people around and dictate what needs to be prepared before the ambulance arrives. Finally the victim is present, only to show that he is not the average gangster or policeman, instead it is the near lifeless body of your own son. Your blood freezes; your brain shuts down, as you see every precious second slip away through the lifeless gaze of your child's eyes.
