method Resurrection of extinct species

Scientists have two main ways of reviving the animals to extinction. Whether cloning animals from frozen tissue or DNA of close relatives of them now.

How to Genetic variation of a relative

The new technique allows scientists genetically altered the animals present into the genome of the extinct gene per gene. Pigeons have been raised in this way.

1. Scientists decode genome

Decoding the genome of pigeons and doves, Miliband Patel pigeons genetic material taken from a tire stuffed a utility that can decode science and 50 percent.

2. Genome pigeons.

When you map the genomes of two species. Scientists will change the genes of Dove Mountain Band of pigeons into the genes. The genome contains genes for both types of birds.

3. genome into stem cells.

Genome been adapted to be inserted into the stem cells. And transformed into germ cells. That is, cells that develop into testes or ovaries.

4. pigeons birth

Stem cells are brought into the band Dove's Nest Hotel. And causes the embryo of pigeons. The virtues of this new science will be gradual. Transformed it into pigeons

cloning nucleus

1. Find Cary

The frozen carcass of a mammoth 10,000 years old, scientists found cells with intact nuclei. What is challenging scientists They also do not find Cary as required.

2. Enter the nuclei into the egg cells of an elephant.

Scientist rid of the nucleus in an egg cell of an elephant. Then remove the nucleus of a mammoth into place. However, cells Rheumatology Chang was rare because it will spawn every four years.

3. embryonic development

The development of the embryo begins if fertilization techniques have been tested on animals, mammals, other than elephants ago.

4. The embryo was implanted into a female elephant.

The larvae are then placed in the womb of a female elephant. But to make it to the uterus. The embryo must pass through the membrane that can not be destroyed. If pregnancy does not end.

5. elephant gave birth to a baby mammoth.

Then plan The embryo will develop respectively the past 22 months, the mammoth genome, which looks like it did when it formed 12,000 years ago.
