	Let's just say they are semantic differences and drop it.

	Suffice it to say that foreign DNA can be introduced into almost
any organism, either naturally, or through a variety of artificial means,
some mild (like Calcium Chloride), some harsh (like the recently described
shot-gun technique for plant cells.
	There are a variety of species that foreign DNA cannot be introduced
into, but if somebody wants to do it bad enough, they'll devise the
methodology eventually.
