     * these nucleotides then form chains when in the presence of clay suggesting that life may have formed in the clay rich muds of hot springs and experiments suggest RNA has the raw catalytic power to catalyze its own replication      * these nucleotides then form chains when in the presence of clay suggesting that life may have formed in the clay rich muds of hot springs and experiments suggest RNA has the raw catalytic power to catalyze its own replication 
     * amino acids react with a sulphur-bearing compound called pantetheine which forms thioesters (activated amino acids) which provides the energy which allows the formation of RNA sequences which could bind preferentially to specific amino acids     * amino acids react with a sulphur-bearing compound called pantetheine which forms thioesters (activated amino acids) which provides the energy which allows the formation of RNA sequences which could bind preferentially to specific amino acids
 +    * in 2022, it was shown that if ribonucleoside triphophates are present, lava rock glass can catalyze the synthesis from these into polyribonucleic acid with averages of 100-300 nucleotides in length and thereby create RNA (([[https://pubmed.ncbi.nlm.nih.gov/35588195/|2022: Catalytic Synthesis of Polyribonucleic Acid on Prebiotic Rock Glasses]]))
     * in 2023, researches found that novel RNA genes can form via instantaneous generation of complete DNA palindromes and thus creation of new microRNA genes from previously noncoding DNA sequences (([[https://www.helsinki.fi/en/hilife-helsinki-institute-life-science/news/new-genes-can-arise-nothing]]))     * in 2023, researches found that novel RNA genes can form via instantaneous generation of complete DNA palindromes and thus creation of new microRNA genes from previously noncoding DNA sequences (([[https://www.helsinki.fi/en/hilife-helsinki-institute-life-science/news/new-genes-can-arise-nothing]]))
