【美国人物志】 芭芭拉·麦克林托克(6/10)
芭芭拉·麦克林托克是一位女科学家。她于1902年6月16日出生于美国康涅狄格州的哈特福德。1923年在康乃尔大学农学院获理学学士学位,1927年获植物学博士学位。在20世纪20~30年代,麦克林托克主要在康乃尔大学从事玉米遗传学的研究。Hints:

It is a research center on Long Island, near New York City. McClintock started in a temporary job with the genetics department. A short time later, she accepted a permanent position with the laboratory. This gave her the freedom to continue her research without having to teach or repeatedly ask for financial aid. At Cold Spring Harbor Laboratory, McClintock continued her work with the breakage-fusion-bridge cycle. She found that some corn plant genes acted in an unusual way. They appeared to move from cell to cell during development of corn particles, or kernels. She discovered that the genes moved on and between chromosomes.来自康奈尔大学的一位老朋友马库斯罗迪斯,邀请麦克林托克1941年夏天在冷泉港实验室工作。这是一个位于纽约市附近长岛的一家研究中心。麦克林托克在基因部门开始一份临时工作。此后不久,她获得了实验室的永久职位。这就允许她不再需要教学或者不停的寻求经济帮助也能继续自己的研究。在冷泉港实验室,麦克林托克继续自己关于断裂-融合-桥循环的研究工作。她发现有些玉米的基因以一种特殊的方式表现出来。他们似乎在玉米的粒度或者核进行发展进化时,从一个细胞转移到另一个细胞。她发现基因可以在染色体上或者之间转移。
