Abstract
Cytosine, adenine, guanine, and thymine, but not uracil, have been detected in core samples taken from various depths of the experimental Mohole. The following quantities of bases were found in the deepest core samples available (approximately 25 x 10(6) years old): cytosine, 2.5 microg/5 g; adenine, 0.9 microg/5 g; guanine, 0.2 micro/5 g; thymine and uracil, 0 microg/5 g.
摘要
在取自实验性莫霍钻孔不同深度的岩芯样本中已检测到胞嘧啶、腺嘌呤、鸟嘌呤和胸腺嘧啶，但未检测到尿嘧啶。在可获得的最深岩芯样本（约25×10⁶年历史）中发现了以下碱基含量：胞嘧啶，2.5微克/5克；腺嘌呤，0.9微克/5克；鸟嘌呤，0.2微克/5克；胸腺嘧啶和尿嘧啶，0微克/5克。
