I am batshit so I might as well go with that. 

Recently, I found myself reading this article.

My first thought was, hey they found water is atmospheres far far away. 

Then I got stoned and Professor Keanu had a brilliant thesis: 

Though observation of the universe compositional makeup seems to be relatively consistent across the board.  Habitable zones are almost universally synonymous with liquid water. 

Are amino acids the same everywhere water is the same?  Can they go a multitude of places? Same reliance of oxygen or sulfur dioxcide? Do other bases and base pair counts change anything?

/\ This gets into other ways for DNA to bond.. I'm guessing, I understood the title.

The idea of panspermia becomes a misnomer if you start seeing the same habitable traits everywhere. It becomes stellar systems have icy bodies, ice bodies lead to liquid water.  There doesn't need to be a single source spread throughout with a like primordial soup.  

Assuming like primordial composition the physiology of life would likely follow the same lines of cellular mitosis and structural formation, causing similar kingdoms of life to form regardless of DNA formation - with pressures and gravitational forces acting similarly.

An analogy here would be a suspension vs arched bridge construction to exist in the same laws of physics.
