Cloning is the process of making copies of individuals that occur in nature such as bacteria, insects, plants, invertebrates or vertebrates. The copy is called clones. Clones are genetically identical to their original parent. Development of cloned animals, which have been genetically engineered to produce valuable proteins in their milk. These have uses in medicine, cloning can also save animals from extinction. Cloning would open doors to even more powerful technologies of human genetic information. However there are ethical concerns about cloning. It limits the variation in population. This is a problem for natural selection if the environment changes. Cloning causes concerns about using technique to clone humans in the future. Moreover …show more content…
Genetic information from one species can be transferred to another species using genetic engineering . Offspring resemble their parents because they contain genetic information passed on to them by their parents .
There are two main methods of animal cloning, embryo cloning and nuclear transfer. Clones produced using the embryos method are not identical to its parents because it is a mix of gene from both parents. Cloning animals through nuclear transfer is unproductive . Studies and experiments show the success rate ranges from 0.1 percent to three percent . In the successful clones, problems tend to arise later during the animal 's development to adulthood.
A developing embryo is removed from a pregnant animal at its early stage, before the embryo has its time to become specialised. The cells then are separated and grown in a reproductive laboratory and then transplanted into host mothers. When the offspring are born they are identical to each other and genetically related to the original pregnant animal however not related to their host mother because they contain different genetic information.
The process of cloning animals through nuclear transfer involves replacing the nucleus of an unfertilised egg with the nucleus from a different cell. The spare nucleus can come from an embryo, but if it is from an adult cell, it is then called adult cell cloning. The procedure involves:
➢ Egg cell
The surrogate mother will ultimately give birth to an identical twin to the donor of the somatic cell (“The Process of Cloning”). This process allows people to clone living things of any sort.
Imagine if you lived in a world where everyone was the same and had no physical differences. Everyone would have the exact same DNA. There would be no diversity within the population. If we continue to clone then this may be a possibility for the future. As of now there have been no cloned humans, but we are not too far away from being able to do so. Scientists have been cloning since as early as 1886, and have been cloning animals since 1996 with the birth of Dolly the sheep. Dolly the sheep was created by using reproductive cloning which is used to produce copies of whole animals (Cloning Fact Sheet NHGRI). Furthermore, there are two other types of cloning; therapeutic cloning and gene cloning. Therapeutic cloning is used to produce embryonic stem cells for medical research (Cloning Fact Sheet NHGRI). Gene cloning is used to produce copies of genes or segments of DNA (Cloning Fact Sheet NHGRI). Cloning should not be allowed because it is inhumane and unethical, results in more failure than it does results, and is unfeasible.
Unlike some movies, cloning in real life doesn’t produce a full grown exact replica of someone. A type of cloning that occurs naturally is when identical twins are born (“What Is Cloning?”). Somatic cell nuclear transfer (SCNT) is a type of cloning that has to be done in a lab. In SCNT they take the nucleolus out of an egg cell, replace it with the nucleolus of a somatic cell (body cell with two complete sets of chromosomes), and make the egg cell divide into a blastocyst (“What Is Cloning?”).
This experiment showed that each cell in the early embryo has its own complete set of genetic instructions and can grow into a full organism. ("The History Of Cloning")
The act of cloning a human being comes dangerously close to human beings acting as God. Do human beings have the right to tamper with nature in this way? This essay explores the various ethical issues related to the cloning debate, and seeks answers to this deep philosophical question at the heart of bioethics. As a student of genetic biology and future biologist, this question also has personal relevance. Our science is evolving at a rapid pace. As human cloning becomes increasingly possible, it is important that we analyze the ethics of cloning so that judicious public policy can be created. It is therefore my position that research into cloning should continue to fulfill the fundamental goals of scientific exploration and to explore the possibilities that cloning might have in terms of benefitting human society; on the other hand, there are certainly ethical limits to the practice of cloning. It is important to define those ethical limits, so that scientists understand the best ways to proceed.
As mentioned earlier, cloning is the copying of an organism that results in identical offspring (“Cloning”). Scientists have tried cloning many times on frogs and other organisms (“Cloning”), but when the first mammal to be cloned was successful in 1997, scientists jumped into pools of thoughts to clone humans. The first mammal to be cloned was a sheep named Dolly. The process of cloning Dolly was called Somatic Cell Nuclear Transfer. The nucleus of a somatic stem cell is taken out of the eggs of the
There are two methods of cloning: embryo splitting and nuclear transfer. Embryo splitting involves egg cells being removed from the female donor, which are then fertilised in a laboratory with sperm from a male by
Cloning is a process that involves removing the chromosomes from an animal’s egg cell and replacing them with chromosomes taken from a cell belonging to a different adult animal. The copied material, which has the same genetic makeup as the original, is referred to as a clone. There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning. Cloning is a very delicate process because many cloned animals resemble animals that are born prematurely. The problem seems to found in the genes because certain genes get turned on or off when a cell becomes specialized during development.
Cloning is a topic that has arisen in today’s modern day society and many people have talked about it, positive and negatively. Cloning can fix several problems including that donor donation and even the cloning of extinct animals. Many are against the use of animal cloning claiming it is inhumane and cruel, however, more are for animal cloning. Although many people are against the use of animal cloning, it would eliminate the need
Have you ever wondered what it would be like to have a second you? The process of cloning is something that is not necessarily very new but is something that is constantly being researched and improved. Most commonly in cloning the somatic cell nuclear transfer method is used.This is when you take a somatic cell(any cell other than the sex cells) from the person being cloned and a donor egg cell and extract the nucleus from the donor egg cell replacing it with the nucleus from the somatic cell. This fuses the donor egg and somatic cell together and next is placed in a surrogate organism that gives birth to that cell that was created. That is the process of cloning an organism. The world of cloning is new and mysterious but is something that could very
“Cloning is great. If God made the original, then making copies should be fine”(Douglas Coupland). Around the late 1800s, a man named Hans Adolf Edward Driesch showed how he can make an exact replica of a sea urchin by shaking it and separating the cells. When doing this, he showed that an embryo in early development can grow into its own organism because it has a set of instructions to follow by. This experiment was one of the first ever demonstrations of artificial twinning which recently jump started the research of cloning other organisms. Cloning can either occur naturally like giving birth to twins or it can occur in a lab where scientists are using genetic information from an organism to make another copy of the same organism. It is the process of making an organism identical to another and there are several types of it; reproductive cloning, therapeutic cloning and gene cloning. Reproductive cloning is started as a somatic cell nuclear transfer, the embryo is implanted into a surrogate and then it grows and
Technology has enabled people to realize many things their ancestors would not have even dreamed of. Cloning is absolutely one of them. Having identical twins without being born on the same they is like a dream come true. But what is cloning exactly? Cloning ,particularly in biotechnology, is the process used to create copies of DNA fragment, cells, or organisms. Attempts at cloning might go back to much earlier times such as the attempt made by Hans Dreisch in the late 1800’s to clone a sea urchin, but it was not until 1951, when the first successful clone of frog egg was created, that goal was finally achieved. Still, the world had to wait for another 44 years before the first mammal was cloned. It was certainly sensational when the first cloned mammal, a sheep named Dolly was born on 5th July 1996. Since it was a milestone in human story, Dolly gained a world-wide fame overnight and took its place in the front pages of many newspapers and even tabloids next to celebrities. However, there is a painful twist to this otherwise happy story because the death of Dolly at the age of six brought about an intense debate particularly about the ethical side of cloning and it has been a controversial issue ever since. Despite of all the debate it has caused among
Learning how to clone an animal is a challenging process. Many people ask the question how does one clone an animal? Cloning is a really challenging procedure and can be hard to do successfully. To clone an animal there needs to be an
Cloning occurs organically in nature. An embryo divides into two individuals with identical DNA thus producing twins. This of course is occurring naturally without any special help or intervention from humans. However in this day and age, scientists have taken it upon themselves to try their hand at cloning mammals with an increasing possibility of human cloning on just on the horizon.
The fundamental concept of human cloning is to create a child through science. People argue different reasons why human cloning is beneficial and the defects of do so. The most common technique of human cloning is through somatic cell nuclear transfer. During this process, “the nucleus of a somatic (body) cell is transferred to the cytoplasm of an enucleate egg” (Stocum, 2016). Once the egg is inside, the nucleus is reprogramed by the egg to become a zygote nucleus.
