Ribosomes are composed of rRNA and rDNA |
The graphic to the left depicts a part of a ribosome (Wikipedia).
The caption indicates that ribosomes are composed of both rRNA and rDNA.
Yes, and both rRNA and rDNA are composed of nucleotides.
RNA is composed of "ACGU" nuceotides and DNA is composed of "ACGT" nucleotides (It's In The GenBank - 4).
Those "ACGTU" nucleotides, in groups of three, are the "building blocks" of codons, which make up genes, which do not, I repeat do not, determine your everything as was once believed in the pseudoscience 'Genieology' (On The Origin of Genieology).
But, to put it quite simply, they are all made of atoms as shown in the previous Dredd Blog post of this series (Quantum Biology - 20).
Thus, since ribosomes "evolved" the nuts and bolts of "evolution" is the "evolution of atoms".
A recent PNAS paper provided a file containing ribosome sequences of nucleotides in a FASTA ".fas" format (Evolution of the ribosome at atomic resolution.
Since I am a "trust but verify" kinda blogger, I downloaded the "pnas.1407205111.sd02.fas" FASTA file containing the relevant ribosome sequences.
Anyway, that scientific paper proclaims "at atomic resolution" but displays no atomic detail (they display the genomic detail, not the atomic detail of that genome).
So, I processed the data in that file, which is presented in today's one and only one appendix (QB 21 Appendix).
What is incredible is that when I put my "verify software" to work on their file, the comparison of the rRNA/rDNA in the ribosomes of the 135 different organisms ends up being very uniform (I mean the comparisons of the percentages of each atom type).
Those percentages refer to the number of carbon, hydrogen, nitrogen, and oxygen atoms in each organism's ribosomes ('percentage wise').
Rather than repeat related previous Dredd Blog text, here (for your perusal) instead are links to the hypothetical concept of these "atomic factories" being "small brains" (Small Brains Considered - 6, Small Brains Considered - 7).
That is not my hypothesis.
I'll close with this observation: the closely matching percentages, in the ribosomes of these significantly different organisms, are an indication that ribosomes are not containment entity originators ... especially the containment entities of each of those disparate organism's local ribosome (On The Origin of The Containment Entity, 2, 3, 4, 5, 6, 7).
