Document Summary
To clone an organism, it is not enough for the dna sequence (genome) to be identical. All the necessary information in the dna must be unlocked. Human cloning occurs naturally when identical (monozygotic) twins are produced. Cloning of offspring using adult cells is done with cattle, goats, mice, cats, pigs, and sheep. Cloning is achieved through the process of nuclear transfer. Dolly the sheep was the first clone from an adult cell. Idea information can be unlocked in g0 . This required unlocking the silenced information in dna. This was the real achievement by the researchers that cloned dna. For dolly, the re-programming was not completely successful. Dolly"s telomeres were short, and she died young. Finding dna evidence hair, semen, urine, and saliva. We leave cells behind us wherever we go. Modern laboratory methods can get useful dna information from just a few cells. That adds up to about 3 million nucleotide differences in the entire genome.
