RNA origin of life

Abstract

RNA molekula sadrži genetičku informaciju i ima katalitičku ulogu, te je stoga možemo smatrati pramolekulom života. Njena uloga je vrlo bitna i u danas u biologiji. RNA svijet je razdoblje u prošlosti Zemlje u kojem se život temeljio na RNA molekuli, a teoriju o RNA svijetu postavio je Walter Gilbert 1986. godine. U ovom radu prikazan je moguć razvoj i funkcioniranje RNA svijeta, te njegov prelazak na DNA/protein svijet, te činjenice koje govore u prilog teoriji o RNA svijetu. Opisana je moguća prebiotička sinteza RNA molekule i ribozimi koji su vrlo važni za teoriju o RNA svijetu.RNA molecule stores genetic information and has a catalytic role, which makes us consider it to be the origin of life. It's role is also very important in contemporary biology. The RNA world represents a period in history of Earth in which life was based on the RNA molecule and the RNA world hypothesis was proposed by Walter Gilbert in 1986. This work displays a possible development, functioning of the RNA world, and the transition to DNA/protein world, as well as facts that contribute to the RNA world hypothesis. A possible prebiotic synthesis of the RNA molecule has been described here, as well as rybozymes which are important for the hypothesis
