1. What was the origin of the information now utilized in the transcription/translation/replication to produce protiens?
2. Since the helicase (protein) is required to open the double helix for the process mentioned above in order to produce other helicase proteins then what is the origin of the first helicase?
3. Where does nature develop chromatin outside of already existing living organisms?
Opinion:It likely just didn't start out as what we call DNA or even RNA. It was probably just something simpler that eventually became what we call RNA then DNA.
Fact:Well, we don't have enough facts for that.
Opinion:It is my understanding that not all cells require helicase, since they don't have a double helix or something like that.
Fact:I'm not sure we have the facts for that one.
Opinion:As far as I can tell, it doesn't really matter whether or not chromatin can or can't be produced outside organisms since the first ones probably didn't need them.
Fact:Again, not enought facts to be sure.
I do have one question for you though. If life began on Earth 3.4 bya and complex life only about 500 mya, why is it so hard to believe that it got from simple chemical reactions to cells over those 2.9 bya some-odd years?
