我们研究了在早期地球上存在的一系列潜在条件下建立RNA世界所需的三个关键组成部分的稳定性。核糖，胞嘧啶，和磷酸二酯键的稳定性估计在不同的pH值和温度下通过外推可用的实验数据。我们选择的条件范围从高酸性或碱性热液喷口，到原始海洋中大气CO2分压范围内的温和条件。
We examine the stability of three key components needed to establish an RNA World under a range of potential conditions present on the early earth. The stability of ribose, cytosine, and the phosphodiester bond are estimated at different pH values and temperatures by extrapolating available experimental data. The conditions we have chosen range from highly acidic or alkaline hydrothermal vents, to the milder conditions in a primordial ocean at a range of atmospheric CO2 partial pressures.
