WASHINGTON — There are hundreds of abnormal genes in cloned mice, which explains why so many cloned animals die at or before birth and proves that it would be irresponsible to clone a human being, ...
A clone is simply a cutting—i.e., a severed part of the plant—that grows roots and eventually stabilizes as a genetic replica of its donor. This is possible because each of the plant’s individual ...
Molecular cloning refers to the replication and recombination of DNA molecules. The first cloning experiments were carried out in the 1970s, when restriction endonucleases were discovered. Restriction ...
WEDNESDAY, Jan. 24, 2018 -- The world's first genetically identical monkey clones have been created by Chinese scientists, who say they've broken barriers to human cloning. But both the scientists and ...

The success of cloning mammals through laboratory procedures has been bleak. Less than 10 percent of cloned mammal embryos make it to birth, with most attempts ending in embryonic death, defective ...
Ever since the birth of Dolly the sheep in 1996, human cloning for reproductive purposes has seemed inevitable. Notwithstanding past dubious claims of such an achievement—including one by a company ...
