Why Genetic Resources? "Saving the DNA and the viable cells of the world's endangered animals" Nearly every cell in an animal's body contains the molecules (DNA, RNA, proteins) that specify all the characteristics of the organism. The Frozen Ark Project aims to save the viable cells and the DNA of endangered species. Viable cells can be stored as samples of tissues, sperms, or oocytes. They can be used in various methods for conserving species. Sperms, eggs and embryos can be used to introduce genetic variation into captive-bred species to prevent them dying out due to inbreeding. The rate at which molecular technology is advancing suggests that in the future it may be possible to reconstruct an entire animal by nuclear transfer and cloning. DNA is extremely stable and it can be stored within the cells. If it is kept at very low temperatures (i.e. below -70oC), it can remain effectively intact for hundreds or thousands of years.
The Frozen Ark Laboratory The sequence of 'bases' in the DNA contains the entire specifications of the animal. We can read its genetic code, reconstruct its proteins and other molecules, and then gain insights into its biochemistry, physiology, ecology and evolutionary history, gaining knowledge of great benefit to humans. Such information may also help us to understand why species go extinct, and what are the ecological requirements for survival. The information could provide policy makers and the public with guidance on how and why endangered species should be protected. |
