Re: CHALLENGE: Why should there be an “origin of species”?

NO. I mean non-living matter to live organism conversion... Micelle to liposome to bacteria thing... Where is the cycle? I see only one direction. Let me clarify: 1. Unless/until someone can produce in the lab "Micelle to liposome to bacteria" spontaneous ...

Re: CHALLENGE: Why should there be an “origin of species”?

1. origin is one point, evolution is process. To have cycle, you have to have process. "Micelle to liposome to bacteria thing..." that's evolution... but it's not cycle (unless the bacteria would evolve into micelle) 2. circle-cycle, there's no difference. And that ...

Re: CHALLENGE: Why should there be an “origin of species”?

... relevant to evolution of species, is it? I am NOT talking about "evolution". I am talking about the "origin". Micelle to liposome to bacteria thing... 2. Most chemical reactions are reversible – another example of “cycle” http://www.bbc.co.uk/bitesize/higher/chemistry/images/process_of_equilibrium.jpg ...

Do the simplest bacteria have ribosomes and helicase?

You want a simple answer to a very hard question that hasn't being properly answered in decades? If you want to speculate, just think of a liposome (bilayer of lipids), with some RNA and nucleotides inside. Just for your info, ATP is RNA. Give it time (billions of years), numbers (huge), additional ...

Re: Biochemical and Molecular Test

... transfection. Several different transfection techniques are available, such as calcium phosphate transfection, electroporation, microinjection and liposome transfection. DNA can also be introduced into eukaryotic cells using viruses or bacteria as carriers, the latter is sometimes called bactofection ...
