 Almost all organisms share the same support for genetic information: DNA. We use the same 4-bases system as any other organisms to encode proteins, ribozymes, etc. We also share nearly all of our genome with chimps, and many of our genes are found in very different organisms. An example of this would be the information encoding the ribosomal RNA or proteins. Eukaryotic cells all have nearly the same ribosomes; moreover, these "evolved" ribosomes are only an expansion of those found in prokaryotic cells. 
That means we depend on the exact same chemical compound DNA, and we share a tremendous amount of genetic material with other species.
