All the structures inside of a cell (nucleus and so forth) already existed.
They removed the DNA from the nucleus of a living cell, and replaced it with DNA that was (using chemical processes) artificially created.
The artificial DNA was created by first reverse-engineering the original genome of this species of bacteria; and then modifying it.
They've been trying to do this for something like 15 years. Ergo, (even though the media hasn't reported it); every other bacterium that they've done this DNA replacement procedure on has died.
So, all that has happened is that they've done in effect, a heart transplant with a completely artificial heart on a molecular level. The bacterium could not be 'dead' for long; otherwise the delicate internal structures that allow it to live would not have been able to return to processing food and reproducing.
The bad news- we now have the tools that could really kill us all in a way that is totally unstoppable.
The good news- the conception of algae that eats carbon dioxide and spits out oil products, or eats oil products and spits out carbon dioxide, etc, is in the realm of possibility.
