Todd:
1) RNA can catalyse it’s own replication. This is a rather old experiment now. Also retrovirus don’t need DNA to replicate – they are protein shells and RNA. They hijack the hosts replication system.
2) If I knew that, I wouldn’t be talking to you… I’d be thanking the Nobel committee. There are a number of hypothesis out there. The most popular one is RNA replication.
3) OK, maybe I was being pedantic. You said that DNA somehow needs proteins to survive. It doesn’t.
4) Tons of evidence. Different organisms have different transcriptions and replication mechanisms.
What has ribosomes( I assume you mean this when you say ribozymes or do you mean enzymes? ) got to do with it? The whole point is that RNA catalyses itself. No need for proteins. PS not a postulate, you can see it in action.
