...microporous honeycombs have been shown to concentrate single nucleotides and oligomers of RNA and DNA up to thousands of times their starting concentration ..., a unique system making an RNA world plausible for the first
time...
Look up Martin & Russell's Alkaline Hydrothermal Vent hypothesis.
Could you please help me to understand the following paragraph:
http://journalofcosmology.com/Abiogenesis107.html
.Convective flow both drives the DNA replicating polymerase chain reaction while concurrent thermophoresis accumulates the replicated 143 base pair DNA in bulk solution. The time constant for accumulation is 92 s while DNA is doubled every 50 s.
To my knowledge, ribose is not a naturally occuring molecule, it takes life to make it. I was taught some years ago at Uni that the simplest life was formed by the formation of lipid membranes. These are fatty membranes made of oil, and can apparently form naturally from naturally occuring hydrocarbons derived from methane etc.
I can see lipid membrane from a fatty acid in other words you form a micell and some organic reaction might take place in the micell such as latex polymerization

That is beyond my knowledge, I'm just an artist.
Latex is actually too advanced for the primative life we are talking about. It probably developed later in flowering plants as a defense measure against attack by insects.
The manipulation of hysrocarbons and, notably sulphurous and phospherous compounds would allow for the reproduction of simple lipid cells. The beauty of these cells is they are hydrophobic on the outside and hydrophyllic on the inside allowing for a discreet cell apart from its environment. These lipids can also stand quite high temperatures which is useful if you're living off a hydrothermal vent. These can get as hot as 400 degrees C
due to the depth and pressere.

Yanks any way I just found the original paper .They actually had a DNA template and a polymerase enzyme in place
The first organised life probably used something along the lines of MRNA due to its simplicity. The formation of enzymes and co-enzymes must have been a crucial developmental step both to process the chemicals in the environment and to reproduce. There is no direct evidence of this as far as I know, but For the first two bn years, life hardly seems to have changed at all. The development of transposable RNA must have been a crucial developmental step.
This also might prove interesting...http://news.bbc.co.uk/1/hi/sci/tech/3321819.stm
Yes, that is correct. Although simple viral RNA is the most basic I know of. Some only has 40 or so active bases and have to hijack living cells to reproduce
Interesting the Virus it comes already packaged with enzyme . I had the impression that RNA is not very stable , but apparently packaged as a virus it is.
One thing I don't understand ...many Virus in order to reproduce itself it have to be by DNA ? then a messenger will help to produce proteines based on the virus strand ?
