    The lack of pyrimidine diversity in meteorites remains a mystery


    On the evening of April 26, an international academic journal (Nature Communication) published online a study jointly completed by Hokkaido University, Japan Marine Science and Technology Center (JAMSTEC) and other teams


    Bases, one of the structural components of nucleic acids, have previously been detected in Carbonaceous chondrites


    The research team said that a series of exogenous meteorite organics, including bases, may have been transported to the early Earth during the later heavy bombardment period (also known as the "moon catastrophe", about 4 billion to 3.


    However, so far, only purine bases have been found in meteorites


    The paper shows that in addition to purine bases such as guanine and adenine previously found in meteorites, the research team also detected various pyrimidine bases such as cytosine, uracil and thymine, as well as their isomers, for the first time


    The team believes that these results suggest that such compounds may have been produced by photochemical reactions in the interstellar medium and then incorporated into asteroids during the formation of the solar system
