"Amino acids found in meteorites from space",
===========================
organic chemist w. bonner said he spent 25 years looking for a terrestrial mechanism for homochirality (one handedness) and didn't find in supporting evidence. so concluded that the source must be extraterrestrial.
"perhaps from circularly polarized UV light in the early solar system"
=======================================
using 100% circularly polarized uv light, the most successful lab expers. yielded only 20% excess lefthanded.
but this results was achieve not by production but by destruction. the uv light destroyed a large fraction of the amino acid, and depending on the directional rotation of the circular polarization, one configuration of the molecules suffered significantly more destruction than the other.
so the hunt has moved to extraterrestrial for a solution. so the appeal goes out to future again.
==================
nice try but the 85% is not homochirality of amino acid. and even the authors said the one handedness could be the result of determinism.
the studies continue.

first sentence under dna wikipedia - Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.
so are you saying that's incorrect? or instuctions is not information?
I'm saying that you are reading too much into the word 'information'. The information is simply the accumulated successes of previous generations. That is its only source and meaning.
The information is the memory of successful biochemistry
