Different species have transferred different genes to the nucleus, but all species with mitochondria have... retained... the same core contingent of … - Nick Lane

[Life is] a continuum. I think there are some phase transitions, probably, and the origin of... genetic information is probably one of them. ...[W]e are doing some modeling work to try and work out how evolvable... a geological system [can] be along the path to getting to cell-like things that... most people would understand as life. How far can you go down that line before you have genetic inheritance? ...[A] long way, but you get to a point where... it's no longer evolvable. ...[I]n our modeling, you can get to a point where you're capable of producing s capable of making copies of themselves with a degree of sophistication, but getting beyond that, to specializing to different niches and so on, I don't see the way, without genetic inheritance.

The double helix of DNA... is composed of two long chains [of 'letters'] that snake around each other... each strand providing an exact template for the other. ...[E]ach strand ...contains just four types of letter, with ...billions ...arranged down... the chain. ...3,000 million letters ...make up the human genome ...[T]he same — the same lines of code — can have different effects depending on the context.

I said you [bacteria] are not morphologically complex, you are biochemically awesome.
