Daughterless Carp Project
The Daughterless Carp Project is a scientific project that is seeking to develop an eradication technique for carp. The technique involves genetically modifying European carp so they can only have male offspring. The introduction of daughterless carp into a population will lead to an all-male population, and the species will eventually die out. The technique has been developed for the CSIRO for the control of invasive carp populations in Australia. European carp in Australia European carp were introduced into Australia in the 19th century. As carp are prolific breeders, hardy and highly adaptable, they quickly established themselves in Australia's waterways. In the 1960s, carp appeared in Australia's largest river system, the Murray–Darling basin. The environmental impact of carp has been enormous. Feeding carp stir up the bottom of the river, stirring up mud and increasing turbidity in the water. Because the fish breed in such large numbers, they have come to dominate the riv ...

Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or " knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome. An organism that is generated through genetic engineering is considered to be genetically modified (G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
