With only about 1 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A ＆ M University researchers have been undertaking for the past five years in a project called "Noah’s Ark’.
Noah’s Ark is aimed at collecting eggs, embryos, semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species, should become extinct, Dr. Duane Kraemer, a professor in Texas A ＆ M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a d
A. available panda eggs
B. host animals
C. qualified researchers
D. enough money
