Advantages and disadvantages of cloning of human?

Answer 1

Cloning is the process of making an identical copy of something. In Biology, it collectively refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. The term also covers when organisms such as bacteria, insects or plants reproduce asexually.

Somatic cell nuclear transfer can also be used to create a clonal embryo. The most likely purpose for this is to produce embryos for use in research, particularly stem cell research. This process is also called "research cloning" or "therapeutic cloning." The goal is not to create cloned human beings, but rather to harvest stem cells that can be used to study human development and to potentially treat disease. While a clonal human blastocyst has been created, stem cell lines are yet to be isolated from a clonal source

The term clone is used in horticulture to mean all descendants of a single plant, produced by vegetative reproduction or apomixis. Many horticultural plant cultivars are clones, having been derived from a single individual, multiplied by some process other than sexual reproduction

Clonal derivation exists in nature in some animal species and is referred to as parthenogenesis. An example is the "Little Fire Ant" (Wasmannia auropunctata), which is native to Central and South America but has spread throughout many tropical environments.Many people are for human cloning for many reasons. The most powerful advantage of human cloning is that defective genes would not cause any more illness in human beings. Cloning might be the cure for the most powerful diseases such as cancer, AIDS, Diabetes, stroke, etc. Cloning of cell tissue can take a good cell from existing tissue and grow cloned tissue from it, therefore damaged cells can be replaced. Cloning could also help the infertile have children that are truly their own and not bein

disadvantage

Furthermore, in cloning Dolly, it resulted in the death of many embryos and newborns before success achieved. (The Dolly experiment started with 277 fused eggs, of which only 29 became embryos. All the embryos were transferred to 13 sheep. 1 became pregnant with Dolly.) In addition, even if the human clone survived, it is not guaranteed that it would develop normally. The genetic material in cloning Dolly came from a 6 year old mammal (what is an old stage of sheep). Dolly's chromosomes could be found in older animals only. This finding made scientists start wondering whether Dolly, looking totally normal from its appearance, might have inherited genetic damage that would be shown in older age only or some other abnormalism.

Human cloning transgresses nature, because it is not via the natural reproductive process, which is by a man and a woman. Human cloning is creating life.

Inhumane

Cloning may arouses social side effects. It is ridiculous that reproduction is separated from love and other human relationship. The entire world may use cloning for eugenics that would lead to efforts to selectively breed children who are of more intelligent, heavier and extraordinary.

There are also medical disadvantages in human cloning, which make the benefits less effective. It was first thought that stem cells could only be harvested from embryos, but today?s researchers are finding that any human cell can be manipulated to replace any tissue of the body.
