During her time at the university, she worked with plants treated with x-rays. She also discovered plants with chromosomes that broke without help of radiation. She described this activity as the breakage-fusion-bridge cycle. University officials and professors recognized the importance of McClintock's research. Yet she believed that she was not able to make progress in her position. So she decided to leave the University of Missouri.施泰德劝说密苏尔大学在1936年为麦克林托克提供一份永久职位。她成为助教。她在大学的这段时间里，她在研究经过X射线照射的植物。他同时发现了未经射线照射就出现破坏性一场的植物。并把这一现象称作断裂-融合-桥循环。大学的领导和教授认识到了麦克林托克工作的重要性。但她仍旧认为自己晋升无望。因此她决定离开密苏尔大学。
