voilà j'ai fait quelques retouches à ce travail, mais j'ai surement laissé passé des fautes
Il faut que tu fasses attention aux articles! ils sont quasiments tous mal placé, pose toi bien les question des cas généraux ou particuliers, et évite de reprendre trop souvent la même structure de phrase "make it possible"
Cloning is a very new useful tool to study
early embryo development, or cellular differentiation and its
disorders, at the origin of cancers. Associated with
transgenes, which is a technique of
genome modification by introduction of sequences of DNA, it is
possible to manufacture animals with a gene
that produces an
interesting therapeutic substance.
Nowadays it is the case with
sheeps and cows which produce in their milk or
blood drugs like antibodies or enzymes
that allow
blood coagulation.
Animal cloning would certainly not be so much mediatised if experiments’ interests were confined
only to knowledge
improvement. In fact, it has many ecological and financial interests at the same time.
Animal cloning while a process of disappearance would make it possible to avoid the total extinction of certain species.
Financial interests are multiple, in particular in this new field of research which
Americans call "pharming", kind of hybrid between pharmaceutical research and agronomic. It is a question of manufacturing
farm animal clones (cows, ewe, goat...) genetically modified (transgenic) to produce proteins or drugs. Also
cloning will make possible to create in series
identical animals for laboratories (
all of them having the same genetic anomaly) or to provide human organs by the means of transgenic animals.
