Introduction I am investigating the issues around cloning and whether it is a benefit to us or harmful. 4. Cloning Cloning is asexual reproduction this is when only one parents chromosomes are inherited. This is why they are genetically identical. Examples of organisms that reproduce asexually are 1. Single-celled organisms like archaea, bacteria 2. Many plants 3. Fungi reproduce asexually. There are different types of cloning, all with different cloning technologies and for different purposes; recombinant DNA technology or DNA cloning, reproductive cloning and therapeutic cloning. 4.1 Recombinant DNA or DNA cloning DNA contains the genetic instruction to create an organism. DNA has two strands which go parallel to each other; this is because of the nitrogenous bases that project inwards and takes the space between them. Diagram 1 on the right shows the structure of the DNA. DNA is the most important factor in cloning. The recombinant DNA technology is a technique for creating DNA molecules from unrelated organisms, ?. For example one of the DNA molecules is a bacterial or viral DNA, these are called cloning vectors. They have the ability to accept any other DNA molecule from an organism, which could be a human, monkey or bacterium, but often the bacterium E.Colli is used. If you combine these two DNA molecules, it will allow replication of many copies of the DNA inserted into the cloning vector. Recombinant DNA technology has already been used to create identical copies of the same animals and to create entirely new species; like a GloFish, a type fish which glows a bright fluorescent coloring. Some types of cloning have improved many lives. ...read more.

Imagine due to further investigations we might be able to successfully clone any animal, or anything we wanted. We could save so many species from dying out; we could stop starvation and maybe even grow organs for transplantation so that people would not be dependent on other peoples lives. Maybe near in the future opinions and technology might change and get even more advanced and allow us to all sorts of things, but with everything there is a risk involved, Arguments against human cloning There are so many types of cloning but one of the most controversial topics would be human cloning. There are lots of arguments against human cloning and the consequences and conflicts it could raise on individuals, families and society as a whole. I will be looking at the argument against human cloning which include ethical and other reasons for being against human cloning. Individuals: What would the relationship between a cloned baby and the cloner? If the cloned child knew that he mother was in reality her sister, her father was actually her brother in law, her grandmother was actually her mother, and the mother who would see her self growing up again. These could severely cause the cloned child to feel abnormal and an outcast, and would strongly affect the child?s life in all areas. Reproductive cloning might bring a loss on the uniqueness? of human beings. If a cloned child for example was created for a specific purpose like a replacement from a child who had died, the child would live a life where she or he would suffer form comparisons and memories of another child. They would be affected, as they won?t have their own life-but are forced to have someone else?s. Human rights: Cloned peoples would not have full rights; just now I referred them as ?cloned?, even though they have a heart, brain, soul and body they would still not be seen as human, since they are just copies. ...read more.

Conclusion

If we allow cloning, it would enhance are knowledge about genetic structures and creating healthy and better children however this could lead from one thing to another, even though people might use it for the greater good, it could lead dangerous things, for example it could fall in the wrong hands like Hitler, this could cause a big problem as people now can create superhuman and build a whole army. Overall, by looking at the for and against I believe that therapeutic cloning should be allowed as it will save millions of people and giving us a clear insight to genetic structures, however many people could go against this, as they believe that by using embryos your killing a human, or your ?playing god? I am strongly against human cloning, because you are cloning humans that are not necessary in this world, as the population is already high and I find just not natural to use a cloned humans, as they would suffer, people around them and the uniqueness of human life would vanish. However, people could disagree because they say it would help infertile people to have children and if they lost children they could have the same child again. I do believe that we should understand that we should respect other people?s opinions. Views and religion but if we are not forcing anything upon people and give the choice to do what they think is best, we would still be able to accept cloning. However I do believe that we need very tight regulations so that people do not abuse the technology available. In the end cloning has much potential to save lives, and saving lives is something good so we should embrace it, and use it for the benefit of all. Opinions vary on cloning, and during my investigation I have come to the conclusion that cloning can be beneficial to us in some areas but is not necessary in other regulations. ...read more.

    When one egg has been fertilised, and the egg divides into two separate eggs, each one contains exactly the same DNA hence producing identical twins with exactly the same DNA. Animals can also be cloned artificially. Embryo Splitting is the most effective technique for cloning animals, and is done by duplicating the embryos before they have been converted into tissues.
