On: Close-Up View of DNA Replication

[cortic]

- "Almost all life on earth is based on DNA being copied, or replicated" - Can anyone tell me what they are referring to here? (life on earth that isn't based on DNA)

[kittiepryde → cortic]

RNA I believe. ( Which I only existed at one time, in theory? Or some people think viruses count as life )

i did spend an embarrassing amount of time trying to find an example of RNA life after reading your initial reply lol.

I suppose viruses do count as 'life' in some sense, so fair enough, thanks for clearing that up.

viruses don't count as life. they have no metabolism (but satisfy the other requirements).
