Cloning is bad

Arif Husain '97 on the subject of cloning ["Critics of Cloning Can't Accept Change," March 21], let us look at the problems that humans have already. We have not realized a peaceful world.

Email Cloned mice developed obesity when they reached adulthood, according to a new study that raises doubts about cloning animals for human transplantation and about cloning humans themselves. Ian Wilmut, the pioneer researcher who cloned the sheep Dolly, says the report raises the question of whether any clones are entirely normal.

Sakai at the University of Cincinnati College of Medicine. The cloned mice were not merely larger than normal mice. They showed several characteristics of obesity, including a significantly higher percentage of body fat and increased levels of insulin and leptin in their blood, Sakai reported.

Insulin is used by the body in the processing of Cloning is bad and other carbohydrates. Leptin is a hormone thought to be an appetite suppressant; excessive amounts can indicate resistance to its effects. In cloning, scientists remove the nucleus from an egg and replace it with the nucleus from an adult cell, which contains the DNA of the donor.

The egg is allowed to develop into an embryo. The cloned mice were compared to two other groups of mice.

One group reproduced naturally; a second - called IVEM - mated normally, but the embryo was then removed and developed in the same lab setting as the clones.

This indicates that either the donor cells used or the method of transfer itself may be related to the development of obesity, Sakai concluded. In a commentary accompanying Sakai's paper, Wilmut said, "It is questionable whether there are any clones that are entirely normal.

Inscientists noticed that the cells in her body had started to show signs of wear more typical of an older animal. Worldwide, there are now hundreds of animal clones, including cows, pigs, mice and goats, many of them appearing healthy. But many attempts to clone animals have ended in failure, with deformed fetuses that died in the womb, had oversized organs or were born dead.

Still others died days after being born, some twice as large as they should have been. The successes and failures of cloning have generated heated debate in many countries, particularly as some scientists have suggested cloning humans.

But the group said that cloning should be allowed to produce cells that promise to treat disease. In so-called therapeutic cloning there is no attempt to produce another live human. Instead, cloned cells only develop into the blastocyst stage - 30 to cells - to produce stem cells that may be used in medical treatment.

Queen Elizabeth, the Clone-Loving Bitch. As he revealed on Facebook in , Donald Marshall, a clone himself, is an otherwise normal guy who had the bad luck of finding himself in a so-called.

EASIS Drive Cloning helps you cloning or copying hard drives, partitions or other storage devices bit-wise. Often you need to copy bytes from one hard drive to a second for upgrade your computer or laptop. Cloning as a technology is considered a bad idea at its current level of development because it raises a number of ethical and biological concerns.

These include the non-viability of many cloned fetuses, the development of physiological disorders later in life, the increased susceptibility to communicable diseases and other circumstances. The dangers of human cloning were dramatically underlined yesterday. A review of all the world's cloned animals found clear evidence that they are at risk of a catalogue of abnormalities.
