and genome engineering technologies, he and other scientists are dreaming up ambitious plans to resurrect long-dead animals from pigeons to Tasmanian tigers and wooly mammoths.
With extinct animals, scientists need to take more involved measures to recover the complete DNA sequence oe its genome.
Armed with this code, they then need to find a way of engineering a regular pigeon's stem cells into behaving like a passenger pigeon's stem cells by mutating the genome.
Church says the complete genome of the passenger pigeon from museum specimens will soon be published and researchers are beginning to alter the genetic make-up of a more familiar bird oe the chicken oe to practice their techniques."
Church admits that bringing it back to life requires a significant improvement in existing genome engineering technologies.
To endow ordinary lab mice with these traits Church will try to partially rewrite the genomes of mouse stem cells.
 Poinar says that genome engineering offers a more realistic shot at resurrecting woolly mammoths and other long-extinct species. Ten thousand-year-old cells and their nuclei may be degraded too to be used in cloning,
This genome is shredded into short fragments, but DNA sequencing machines can read these shards and powerful computers can stitch them into a genome sequence.
Scientists published a 80%complete version of the mammoth genome in 2008 and more ancient animal genomes are on the way,
such as the Tasmanian tiger. These genomes exist in the form of computerised data, but they could serve as a blueprint for altering the DNA of a cell from a closely related species. For instance,
the code of a woolly mammoth's genome differs from an African elephant's by roughly 240,000 DNA letters out of a total of 4 billion,
though most of these changes are not likely to have a biological effect. An elephant ips cell engineered to contain those mutations would theoretically be capable of producing woolly mammoth sperm.
Better yet the woolly mammoth stem cells could be implanted besides an elephant embryo early in development,
or indeed any extinct species would require a dizzying list of technological leaps in genome engineering, reproductive biology,

Other next-generation crops will be created using advanced genetic manipulation techniques that allow high-precision editing of the plant s own genome.
But figuring out how to make changes in the genomes of more complicated organisms has been tough.

and there are questions about how stable the revised genomes of these cells would be over time.
what's in the nucleus. Trying to treat a mitochondrial disease by turning back the clock on an adult cell's genome would do nothing
and insert it in the place of the egg's original nucleus. Now that adult cell's genome can hum along in its new home creating stem cells without the mitochondrial defects present in its original form.
because they no longer have fully intact genomes. But there could be another way: Using fragments of the passenger pigeon DNA scientists could synthesize the genes for certain traits and splice the genes together into the genome of a rock pigeon.
The cells containing the passenger pigeon DNA could be transformed into cells that produce eggs and sperm

which bind to specific sites in a genome and then cut nearby strands of DNA.
Plant biologists have long been frustrated by the lack of a simple method for either deleting a specific gene from the genome or replacing it with another gene.

The bacterium Agrobacterium tumefaciens which can cause tumours on plants shuttled foreign genes into plant genomes.
By revealing similar elements in plants'DNA, genome sequencing has liberated developers from having to borrow the viral sequences.
Many companies are developing'mini-chromosomes'that can function in a plant cell without needing to be integrated into the plant's genome.
Other techniques under development insert foreign genes into designated sites in the genome, unlike the near-random scattering generated by Agrobacterium.
and Sangamo Biosciences in Richmond, California, announced that they had used enzymes called zinc-finger nucleases to insert a gene for herbicide resistance at a specific site in the maize genome (V. K. Shukla et al.
because the techniques available to introduce foreign genes into animal genomes were not precise, and misplaced genes failed to express themselves correctly.
They inserted DNA encoding a version of this microrna into the genome to create genetically modified cow embryos that they hoped would grow into cows without the allergen in their milk.

Some of that DNA is incorporated then into the genome. For Greg Jaffe, director of biotechnology at the Center for Science in the Public interest
