Tiivistelmä
The last universal common ancestor is believed to be an organism from which all modern organisms on earth today are thought to be descended from. LUCA is thought to be the recent most ancestor to all present-day organisms on earth. It would be incorrect to assume that LUCA is the first living organism on earth.
The present study had aimed to classify structural superfamilies, describe the relevant functionality of LUCA and even explain the overall functionality of LUCA’s membranes. A kind of representative protein set was selected to be used in the present thesis. The protein set in this case was specifically compared with a file that had a list of superfamily IDs generated from the CATH website.
The study results infer that LUCA had been seriously endowed with very essential functional properties like synthesis of RNA, DNA, or even proteins most likely to be similar to those that are operating within bacteria. It is equally explained that different subsections of synthetic pathways were differentiated among organisms sharing no relation to each other. This actually explains the existence of very extreme and varied cell walls within modern organisms. The study has shown that as time continued to pass; the walls seemed to have evolved and are actually looking dissimilar with time. The overall findings have shown the core functions well represented with the modern like LUCA. The results in this case actually suggest Heterotrophy-unlike Ranea. The findings have subsequently shown that within the cellular signaling and processes, there are some sorts of common bases within the cell cycle and subsequently within the signaling. The study results have also revealed a cell wall biogenesis, cell motility, cytoskeleton, intracellular trafficking, posttranslational modification, cell cycle control, defense mechanism, and signal transduction mechanism in ALL_ cellular processing and signaling.
