... Mutation in OsRPA1a exhibits abnormal chromosomal fragmentation occurred in male meiocytes after anaphase I. Further study identified that the leaves of Osrpa1a were hypersensitive to DNA mutagens, suggesting that OsRPA1a plays an essential role in DNA repair but may not participate in, or at least ...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
