My first concern (in this origin of life scenario) was, 'could the proto tRNA (tNA) directly h-bond
to an AA. If it can that will solve a lot of prebiotic puzzles IMO.
And let's say for discussion, that the tNA has 4 loops (or 3) and 2 anti codon areas that are
opposite each other.
I found this website - See biochem.ucl.ac.ukmc.htmlOpen ↗
If I'm reading it correctly there are 3 (2 +1) hydrogen bond points on the main part of AA's. This
might line up with an anticodon on a tNA nicely. And how wonderful if it would line up with 2 bases
exactly and a third kinda wobbly!
My question then is there a fit and how is the fit? Is it conceivable that a tNA with an anticodon
area of at least 3 bases - have any 1, 2 or 3 h bond into a short peptide bond?
Comment?

The main points of my hypothesis are:
1. How life began as a reaction to the sun/UV and the thermal cycle of hot-dry-sun/cold-wet-night.
Then continued as an energy moderator with modification through descent.
2. The Four Options and how they relate to thermodynamics, biological classification, the first
cell, modification on all levels, psychological behavior of individuals and groups, inner
conflicts and a therapy of resolving them, etc.
3. Model showing relationship between adaptation fitness and natural selection. How it supports
punctuated equilibrium and the 'slope and plateau' model etc.
