5) but preceded the emergence of eukaryotes and even LUCA.
Eukaryotes have maintained their introns because they confer the capacity to create evolutionary novelty through exon shuffling [ 2 ] . The introns-early theory predicts that at least some of the extant eukaryotic introns are direct descendants of the primordial sequences in the LUCA [ 2 3 4 5 ] . The alternate view, "introns-late", suggests that the last common ancestor was intron-free and that spliceosomal introns have originated in eukaryotes from recent invasions by autocatalytic RNAs (e.g.
The above analysis shows that LUCA probably encoded three distinct DPBB domains.
Hence, considerable diversity of protein domains appears to have emerged prior to the "crystallization" [ 95 ] of a transcription machinery similar to the one that operates in modern cells and probably had been already in place in LUCA [ 96 ] . Similar conclusions regarding the early stages of protein domain evolution have been reached previously as a result of evolutionary analysis of proteins involved in translation, such as aminoacyl-tRNA synthetases and GTPases: substantial diversification of protein domains had occurred prior to the "crystallization" of elaborate, modern-type translation machinery [ 66 97 ] .
Although the sequences of the Zn-ribbons of bacterial and archaeo-eukaryotic DDRP subunits have diverged considerably, their similar location in the orthologous polypeptides from different kingdoms suggests that β' subunit of LUCA already contained a Zn-ribbon.
