Tracing the evolution of structural change in rRNA. The ability to trace structural features evolving along the lineages of the universal tree using parsimony-based methods offers a unique opportunity to study how evolutionary change is distributed and constrained in rRNA.

Tracing the evolution of structures important for ribosomal function A number of structures important for ribosome function have been recently identified in the interface of the two rRNA subunits, located in an RNA core devoid of ribosomal proteins ( 6 ).

RNA structures can be represented by arc-annotated sequences (primary sequence along with arc annotations), and this paper mainly focuses on the so-called arc-preserving subsequence (APS) problem where, given two arc-annotated sequences (S, P) and (T, Q), we are asking whether (T, Q) can be obtained from (S, P) by deleting some of its bases ...

In the earliest stages of ribosome evolution, the cellular entities carrying “protoribosomes” would have lacked a genetic code and the complex dynamic systems of the modern ribosome. Such an entity would thus be in the “throes of evolving the genotype-phenotype relationship” and would be properly considered to be a progenote ( Woese and Fox 1977 ).

Abstract. Ribosomes are the only cell organelles occurring in all organisms. E. coli ribosomes, which are the best characterized particles, consist of three RNAs and 53 proteins. All components have been isolated and characterized by chemical, physical and immunological methods. The primary structures of the RNAs and of all the proteins are known.

In the model, history in RNA structure is also remembered and recovered with high explanatory power by the phylogenetic model of nucleic acid evolution. Recovery is even roughly congruent with nomothetic models once the core–periphery assumption of ‘rooting’ is removed (Fig. 7). The ribosome carries functions that are ‘processive’, i.e. functions that uniquely …

https://pubmed.ncbi.nlm.nih.gov/18430223/
Background: The origin and early evolution of the active site of the ribosome can be elucidated through an analysis of the ribosomal proteins' taxonomic block structures and their RNA interactions. Comparison between the two subunits, exploiting the detailed three-dimensional structures of the bacterial and archaeal ribosomes, is especially informative.

Evolution of structure in RNA.
https://www.ncbi.nlm.nih.gov/pubmed/6201210
Evidence is presented that structures formed by RNA and by RNA in association with protein have evolved from simpler structures by successive unions among them. The progressively more complex molecular structures have conferred selective advantage in evolution by progressively enhancing the specificities of the biochemical reactions.
