Despite several highly publicized claims,
All of the steps in cloning are complicated which means it has a high failure rate. Only a few percent of attempts are successful, meaning that scientists have to try many times to make a clone. In fact, Dolly was the only success out of 276 cloning attempts! Each attempt is very hard work and takes a long time.
On Dec. 27, 2002, Brigitte Boisselier held a press conference in Florida, announcing the birth of the first human clone, called Eve.
Some scientists believe clones would face health problems ranging from subtle but potentially lethal flaws to outright deformity. But let's ignore all that--for the moment--and cut to the bottom line: How much would it cost to clone a person? According to our estimates: about $1.7 million.
The processes of human cloning could help to create new advances in medical science. By creating a duplicated individual, it would become possible to share genetic material which could help to prevent or cure diseases that may have a negative impact on that person's life.
The predominate theme underlying arguments against human cloning is that the cloned child would undergo some sort of physical, social, mental, or emotional harm. Because of these and other concerns, the United Nations and many countries have banned human cloning.
The first is that cloning takes away genetic diversity, which could make a child more susceptible to a range of issues. This includes cancer, genetic malfunction and shortened lifespan. Although cloning can be used to treat genetic disorders, it can end up perpetuating them as well.
1 No one has ever cloned a human being, though scientists have cloned animals other than Dolly, including dogs, pigs, cows, horses and cats. Part of the reason is that cloning can introduce profound genetic errors, which can result in early and painful death.
The Problem of DNA
DNA has a half-life of only 521 years, and it's easy to contaminate or destroy. Which means that it's virtually impossible to clone in the only way that we know how to do - with the transfer of DNA from one individual into an egg cell.
Windpipe transplant breakthrough - Scientists (including surgeon Paolo Macchiarini) have carried out the world's first tissue-engineered whole organ transplant made with a patient's own stem cells.
That would be Kix. Due to his being frozen in stasis by the Separatists, he survived for 50 years after the end of the Clone Wars before being awakened by a pirate gang several years before the events of the sequel trilogy. Kix, Able, or that one Delta squad guy that appeared in legacy of the Force.
If the average life expectancy of humans in the galaxy far, far away is similar to our own, it's about 70 years for men, meaning that clone life expectancy can be halved to just 35 years.
Grand Army of the Republic lived the longest? well, it's none other than CT6116 or Kix of the 501st Legion. kix served alongside Anakin Skywalker. and Captain Rex during the Clone Wars as a medic.
Where is Dolly now? After her death The Roslin Institute donated Dolly's body to the National Museum of Scotland in Edinburgh, where she has become one of the museum's most popular exhibits.
Human cloning is banned across the world because of the following reasons: It is never ethical to sacrifice one human life to get the potential cells for cloning for the real or potential benefit of others. Research cloning will undoubtedly lead to a new exploitation of women.
A clone is a biological duplicate that does not share the mental history of the original. There is no known technology that could input all of one's experience and make an exact duplicate, including every thought, memory, and emotion. So from that perspective, a clone would not know he or she is a clone unless...
The oldest DNA fragments recovered are only 800,000 years old, so dinosaur cloning is probably impossible.
Human beings should not be cloned for several reasons that are going to be further discussed in this op-ed: cloning is a risky, imperfect procedure, it does not create an exact copy of an individual, and it poses ethical concerns by using human beings as a means to an end, opening up possibilities for abuse and ...
While the data answer many questions about such issues as Neanderthal language capacity and the genes they passed onto humans through interbreeding, we're still a long way from being able to resurrect one.

Even though a clone is genetically identical to its host, a clone would not have the same fingerprints as its host because fingerprints are not genetically determined, rather they are formed in the womb as result of external processes.
You've probably heard of Dolly the sheep. Now, meet Elizabeth Ann, the black-footed ferret. Scientists have successfully cloned an endangered black-footed ferret, using preserved cells from a long-dead wild animal.
They were designed to age twice as fast as a typical human. With that in mind, clones that were only 10 years old were the equivalent of 20-year-old men.
These include an increase in birth size and a variety of defects in vital organs, such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system. Another potential problem centers on the relative age of the cloned cell's chromosomes.
Human cloning could also increase the risk of birth defects if cloned individuals begin marrying nearly identical genetic relatives, a danger that will be hard to avoid in second and third generations. Of course, it is important that we not overstate the case by exaggerating health risks associated with human cloning.
