"Reactive oxygen species (ROS) are produced as byproducts of metabolism. In germline cells, ROS are likely a significant cause of DNA damages that, upon DNA replication, lead to mutations. 8-Oxoguanine, an oxidized derivative of guanine, is produced by spontaneous oxidation in the germline cells of mice, and during the cell's DNA replication cause GC to TA transversion mutations. Such mutations occur throughout the mouse chromosomes as well as during differen… " - In humans where are germline cells found
