Abstract
Iako nije poznato koji su selektivni pritisci utjecali na nastanak i ranu evoluciju DNA, neosporno je da je prelazak s RNA na DNA genome jedan od ključnih događaja u evoluciji života. S obzirom na to da je replikacija esencijalan proces u svim živućim stanicama, koje su potekle od zajedničkog pretka, logična bi pretpostavka bila da je osnovna replikacijska mašinerija homologna u svim trima domenama živog svijeta – bakterijama, arhejama i eukariotima. Međutim, većina enzima koji sudjeluju u molekularnom mehanizmu replikacije nisu homologni u svim domenama života, što je podudarno s neovisnim nastancima replikacije DNA. Na kraju rada ću iznijeti hipotezu prema kojoj su virusi prethodili staničnom životu i potencijalno predstavljaju poveznicu između DNA i RNA svijeta
Abstract (english)
While it remains uncertain which selective pressures influenced the origin and early evolution of DNA, the transition from RNA to DNA genomes is undoubtedly a key event in the history of life. Since replication is an essential process in all living cells, which share a common ancestor, a reasonable assumption would be that the fundamental replication machinery is homologous across all three domains of life: Bacteria, Archaea, and Eukarya. Nonetheless, most enzymes that play a role in the molecular mechanism of replication are not homologous across all domains of life, which aligns with the idea of multiple independent inventions of DNA replication. Lastly, I will discuss a hypothesis that proposes viruses predated cellular life and might serve as the missing link between the RNA and DNA worlds.
