Chicken Pox Only On Leg

Barbara McClintock, nació en Hatford, Conetica el 16 de junio de 1902 y murió el 3 de Septiembre de 1992.
Desde pequeña, en Connecticut, Barbara ya era una amante de la naturaleza. A menudo pasaba períodos en el campo con sus tíos, donde aprendió a reparar máquinas y reforzó su amor por la naturaleza.
Después de la secundaria quiso seguir estudios universitarios y su madre se opuso, temiendo que la calificaran de "rara" y que le ahuyentara a futuros pretendientes. Gracias al apoyo de su padre, finalmente E n 1919 se matricula en la facultad de agronomía de la Universidad de Cornell y se doctorate in botany in 1927 .. As an advanced student, Barbara made her first major contribution to science has identified 10 chromosomes of maize.
In 1927 his cell analysis of maize was first demonstrated by visual evidence that interbreeding organisms is accompanied by a physical exchange between homologous chromosomes.
TransAl in 1936 to work at the University of Missouri for five years, teaching botany. By 1940, following his study of maize chromosomes interpretation of the data led to affirm the existence of genes as "drivers" that activate and deactivate other genes. In 1941 he secured a position in the department of genetics at the Carnegie Institution in Colds Spring Harbor on Long Island.

The theory of the elements "translocated", which would be awarded thirty-five years later, was filed in 1951 and went unnoticed. His theory was revived in 1970 and in 1983 was awarded the Nobel Prize. Despite these difficulties, she continued to work in corn genetics and evolution of indigenous farming until 1992 when he died.
His outstanding contributions to cytology and genetics revolutionized science and contributed to the understanding of human heredity, the cause of certain diseases and the ability of bacteria to change and resist antibiotics, among others.
