Probably not chemically identical, but similar. Different nucleotides and protein sequences, but you'd certainly see alot of the same structures (alpha helix, beta pleated sheet, etc.) and things like methylation. I would expect this based on the fact that DNA is incredibly information dense, so it would be surprising if the universe had completely novel ways to optimize for that problem.
