This video, which is a part of the Distinguished Lecture Series by Trivedi School of Biosciences, Ashoka University, Prof. Jack W. Szostak discusses why life began with RNA. Why was Ribose sugar chosen in the primordial soup, and not several other alternative sugars that may have been available? He shows this using elegant experiments that include chemistry and structural biology.
Distinguished Speaker: Prof. Jack W. Szostak
2009 Nobel Laureate in Physiology or Medicine

This is all fascinating (and it must have been a LOT of work to figure this all out!).

Szostak has demonstrated that RNA is highly favored in replication. I assume this is under "normal" laboratory conditions approximating current conditions on earth in terms of temperature, pressure, ph and salinity. He then asks if this favor towards RNA would be shown to extra-terrestrial life forming on other worlds. The answer would seem to be in changing the previously mentioned laboratory conditions given the improbability of these prevailing on other worlds and given how much these factors can change the reaction rates of chemical processes. The answer to Szostak's question should therefore be sought there. In general I think we need to look outside easy to work with current terrestrial conditions if we want to understand early pre-biotic conditions from which life can form spontaneously from geology.

Beta ribo cytidine is faster than its stereoisomers (Different shapes) - duh. I shall decline my Nobel Prize - anyone can take this. Thx.

Human will never be able to create life from non -life. It is the almighty God created life out of water- "Do not those who disbelieve see that the heavens and the Earth were meshed together then We ripped them apart? And then We made of water everything living? Would they still not believe" Quran 21:30.

I wish biologists resort to finite axiom algorithm of a QC function and read out data from finite gate quantum circuit, much like Hameroff used coherent quantum system of microtubules, that satisfied Penrose who took upon himself to investigate consciousness.

Doesn't that rely on spontaneity? That would make it only hypocritical at best.

Life and consciousness is a QC function, that carries physics into metaphysics, as quantum fields collapse the field into particles that then leads to life, soul and faith.

@@sonarbangla8711 that isn't an answer. I guess I should have expected this. Also, is faith used in a mathematical calculation?

The entire problem you have is rna cannot exist without dna and visa versa. They have to have both come into existence at the same time. It's the same problem with all of the physical world. It is so interdependent.

Its RNA because there is no other story to tell. I would like to hear how RNA didn’t react with itself and degrade in your story and how DNA was created from a RNA world when proteins are first required to make DNA.
