The Importance Of The Cloning Of Dolly The Sheep - 1743 Words

The cloning of Dolly the sheep from a differentiated adult mammary epithelial cell was a crucial turning point for the revolution of science. It indicated that nuclear reprogramming can completely re-activate genes after being inactivated during tissue differentiation. There is enormous potential application in cloning by nuclear transfer using mammalian somatic cells However, somatic cloning used in producing live clones have resulted in defects and high fetal mortality rates. Therefore, the cloning of animals should be discontinued as it is unethical and inefficient. Livestock agriculture has applied a selection criteria in order to foster the propagation of animals with desirable traits and multiply copies of genetically elite farm†¦show more content†¦As can be seen in the diagram, the nucleus is removed by microaspiration, using a finely honed needle called a micropipette. Fusing the membranes that separate the ooplast and the donor nucleus must first be executed before the development process can occur. The fusion stage can be carried out through two separate processes, either by applying a brief electrical pulse, or through chemical fusion. Fusion by electrical stimulation is the more commonly used technique. It involves a mild electrical current being applied in one to several microbursts in the proximity of the cells. This results in the formation of pores between the somatic donor cell and ooplast which fuses the two cells into one. Embryonic development is also stimulated from the newly formed cell, resulting in the growth of blastocysts that are transplanted into surrogate mothers. Coordination of the cell cycle stage of the donor nucleus and the recipient egg cytoplasm are important in determining the successful development of embryos. When the developing clone reaches the blastocyst stage it is transferred into a surrogate mother in which the estrous cycle has been synchronised. The pregnancy is then allowed to proceed naturally after the embryo clones have been transferre d. Although there is relatively low success in animal cloning, with optimization it promises great advantages for commerce and research alike.

Cloning - Dolly the Sheep Dolly the sheep was a part of research in Roslin Institute as they were looking into producing medicines through milk of farm animals.

In 1997 Scottish scientists created the first cloned mammal, a sheep named Dolly.

These individuals argue that cloning can and should be used for medical purposes, and can also provide nations with accessible clones to do â€Å"dirty jobs† or participate in the military forces in order to benefit the country. Others decide that cloning is justifiable in order to replace a deceased child or pet or to even enable infertile couples to have children.

Since the birth of Dolly, the sheep, in 1997 the controversial question of cloning has been paramount throughout the entire globe. The question is no longer whether it can be done, but whether is should be done and to what extent. We have already cloned goats, mice, monkeys, cattle, and pigs (Cloning fact sheet). Scientists are now trying to get approval to clone humans orRead MoreEssay about Analyzing the Ethics of Reproductive Cloning1534 Words   |  7 PagesAnalyzing the Ethics of Reproductive Cloning    â€Å"We hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness† -Thomas Jefferson, The Declaration of Independence (1776)    The notion of the existence of basic human rights which all men are entitled to, first advanced by the great philosopher John Locke, became an indelible part ofRead More The Sins of Cloning Essay1319 Words   |  6 PagesThe Sins of Cloning   Ã‚  Ã‚   See you in two years with your cloned child, says the doctor to his patient.

In 1953 two scientists by the names of James Watson and Francis Crick discovered the structure of DNA.1 DNA can be defined as the makeup of chromosomes, which carry genetic information. DNA is present in nearly every living organism
