I think nucleic acids like RNA will be somewhat universal because of how versatile and robust it is. RNA can encode genetic info, can be an enzyme without having to form a protein, etc.

I think the big difference will be the "power plants" of their cells. The chance of the endosymbiotic events like what happened here on Earth (once to get the mitochondrion and again to pick up the chloroplast) being similar are minuscule.

I can see life picking up multiple "external" origin organelles on a different planet before developing structure and complexity in body form.

Hi /sci/

Theoretical biology question. In HP Lovecraft's 'In the Mountains of Madness" the Elder Things physically traveled to the Earth from their homeworld by 'flying through space' using their wings and siphons for propulsion. This trip took thousands, if not millions of years for them to complete.

My question relates to cosmic radiation. (1) How might they survive such levels of radiation, and (2) when they finally descend to a planetary biosphere, how long - or will they - be radioactive and deadly to local flora and fauna?
