Here is were I support cloning, to help endangered speices, or bring some back (tasmanings Tiger I belive)

SEOUL - South Korean scientists, once led by disgraced stem cell researcher Hwang Woo-suk, said on Monday they had created the world's first cloned wolves, which were produced to help an endangered species.

A team at Seoul National University, which produced the world's first cloned dog in 2005 — an Afghan hound named Snuppy — showed off the the two Korean wolves named Snuwolf and Snuwolffy that were born a year and a half ago.

It took the team a while to publish its findings likely because of extra scrutiny due to being implicated in fraud, a member said.

"Normally, scientific periodicals would not ask for mitochondrial DNA verification but we needed to produce it due to previous problems," said Lee Byung-chun, a professor who heads the research team.

Lee said the quarterly periodical "Cloning and Stem Cells" will publish the team's findings its upcoming issue.

Lee said cloning Korean wolf could help the species survive. Wolves have not been spotted in the wild in South Korea for about 20 years, Lee said, and the only ones that are known to exist in the South are in a small pack of about 10 at a nature park in Seoul.

Snuppy was dubbed one of the most amazing inventions of 2005 by Time magazine. Independent testing has concluded the dog was an actual clone.

Hwang and other members have since left their posts at the university after his team fabricated data in two papers on human embryonic stem cells that have since been debunked.

Hwang is facing trial on fraud, embezzlement and violating the country's bioethics laws.

In December, the team said it had cloned three more Afghan hounds and improved the efficiency of its cloning methods.

For the wolf cloning, it transferred 251 reconstructed embryos to 12 surrogate mothers to produce two living clones.

Dogs are considered among the most difficult mammals to clone because of their reproductive cycle.

Wow. That's something we all should learn to do. We could bring back many species.

They should definatly do it for the Galopogous[spell check] Turtles

That wont work unless that have a complete cell to use for the cloneing process, not just DNA. If all you have is DNA, you cannot clone an animal, you need a cell from that specific animal, cause only about 95% of the neccessary info for the cell to grow is located in the DNA, the other 5% is in the cytoplasm of the cell. Without it, its useless.

So if the animal is only recently endangered will cloning them work, though I support that idea sence it saves a lost species.

Lol, its interesting what you learn from Biology class...

Yeah but the DNA doesent toal deteriate for a long time. So thay cant currently bring back like dinosaurs, but cant they bring back like the dodo bird?

If they have a cell of the creature and some of the cytoplasm of that cell, then yes. Otherwise, no, its imposible. And it is imposible to bring dinos back, as there are no intact cytoplasm from them. Now Mammoths are a different story, theres a slight hope for them... They just need something that can give birth to it, sence they cant use a normal elephant, their way too small.

for cloning dont they like keep copying the DNA
