Every organism on Earth relies on the same genetic building blocks: the the information carried in DNA. But there is another class of genetic building block called "XNA" — a synthetic polymer that can carry the same information as DNA, but with a different assemblage of molecules.
XNA is synthetic DNA that’s stronger than the real thing
On the second line are atomic numbers of the basic elements which humans thought (in 1974) made up the foundations of Life -- hydrogen, carbon, nitrogen, oxygen and phosphorus.
So, what about those changes? To begin with, the first line -- the decimal equivalents of the binary code -- were unchanged. But the atomic numbers of the elements composing the basis of Life had been altered: silicon, an element with an atomic number of 14, was added precisely in the correct sequence -- between oxygen (atomic number 8) and phosphorus (atomic number 15). This was a most curious and significant addition.

Silicones are polymers that include silicon together with carbon, hydrogen, oxygen, and sometimes other chemical elements. Some common forms include silicone oil, silicone grease, silicone rubber, and silicone resin.

This is just wrong. Scientist trying to play God.

This is very much worth investigating IMO. This could give us new insight into how we got here; furthermore, it can provide insight to what is possible on other planets.

If the military thought modern genetics were neat, I am sure the rather terrible ideas never stop flowing when even basic rules of life can be bent and re-defined.
Synthetic biology is already a burgeoning....created the world’s first synthetic cell, with a chromosome produced by a machine, and we’ve seen a host of other bio-engineering breakthroughs like cells that communicate like electronic circuits, artificial proteins that can sustain life. www.popsci.com...

Time after time people wave their arms about and regurgitate programming like "they're playing god", "if man was meant to fly he'd have wings".
I wonder how many that have spouted such have typed out those responses on the latest 4G smart phone.
Look at the technology you're using to reply with these Luddite parroted phrases.
If man was meant to communicate over vast distances near instantaneously, he'd be like gawd. OMG being on the internets is playing gawd?
Of course, saying that something is akin to 'playing god' only counts when it's convenient for whatever bias against whatever technology you want to bash is convenient.
It's not playing god. Man invented god. It's being human. We have the tools (created, or evolved, regardless your argument) between our ears to do these things, to observe the universe and everything in it from the very small to the very large, and change them to suit any purpose we might imagine for them.
If you're a creationist, then, gawd gave this ability to us fair and square. He/She/It/They wouldn't have given us this ability or even the thing or avenue to pursue if it wasn't meant to be poked at, examined, and possibly even changed, customized, or improved on.
If gawd wanted that tree turned into a dining room table or a door for your house, then that tree would have growed that way. Chopping a tree down and turning into something else is playing gawd.
Please tell me you get the gist of that, and no, it's not any different. Tree, banana, fish, DNA, it doesn't matter.
Corn is entirely unnatural and is the result of thousands of years of human selection for bigger meatier kernels. Corn looked more like wheat before man started growing it and selecting the bigger returns, and seeding the bigger returns over and over and over across thousands of years.
Does that make corn the devil?

The finding is a proof of principle that life needn't be based on DNA and RNA. Astrobiologists have long suspected as much.
"This is very interesting with respect to the origin of life," says Jack Szostak of Harvard University in Boston, Massachusetts. Nowadays, all life-forms use either DNA or RNA to store genetic information. Many biologists suspect that the first life-forms used RNA, and DNA was adopted later. But we don't know why those two molecules were chosen: are they the best possible storage media, or were they simply the only things available?
Holliger suspects RNA was an opportunistic choice. "Clearly, there is no overwhelming functional imperative to use DNA and RNA," he says. Instead, life may have started with RNA simply because it was made in large quantities on the early Earth.
Most biologists think life on Earth began with RNA because it can both store information and catalyse useful reactions. In his latest experiment, Holliger has now shown that one of his XNA's – 1,5-anhydrohexitol nucleic acid, or HNA – can fold into a 3D shape and bind to specific target molecules. This is the first step in becoming an enzyme. The same thing had previously been done for threose nucleic acid (TNA).
This suggests XNAs might form the basis of life on other planets, where different environments led to different chemistry. "I would be surprised if we find truly extraterrestrial life that was based on DNA and RNA," Holliger says. "There might have been an XNA-world on a different planet."
