The paper you cite about the bacterium that uses arsenic instead of phosphorus in its DNA was conclusively discredited. http://www.nature.com/news/arsenic-life-bacterium-prefers-ph...

This does not mean that arsenate does not get into the bacteria, he points out. β€œIt just shows that this bacterium has evolved to extract phosphate under almost all circumstances.”

Yes, it really wants phosphorus. But, a strong preference does not create phosphorus when there is none to be found.

Not that single cells really want or try etc, but you get the idea.
