Experimento de Griffith. En 1928, el microbiólogo Fred Griffith, que investigaba varias cepas de pneumococcus, inyectó ratones con la cepa S y la cepa R de la bacteria . La cepa S era dañina, mientras que la rugosa (R), no lo era. Cuando, inactiva por calor, la cepa S era inyectada, no había secuelas y el ratón vivía. O famoso experimento de Griffith de 1928 nos mostrou que as bactérias podem alterar nitidamente sua função e forma por meio da transformação. Transformação é o processo que descreve uma coisa se transformando em outra. Em seu experimento, Griffin injetou dois tipos de Streptococcus pneumoniae, Tipo III-S e Tipo II-R, em camundongos. Griffith's experiment discovering the "transforming principle" in Streptococcus pneumoniae (pneumococcal) bacteria. Griffith's experiment, [1] performed by Frederick Griffith and reported in 1928, [2] was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. [3 In 1928, in an attempt to develop a vaccine against pneumonia, Frederick Griffith became the first to identify bacterial transformation, in which the form and function of a bacterium changes. He discovered a "transforming principle" that was responsible for converting an avirulent R strain of Streptococcus pneumoniae into a virulent S Alejandro Ocampo. El experimento de Griffith, llevado a cabo en 1928, fue uno de los primeros experimentos que demostró que las bacterias eran capaces de transferir información genética mediante un proceso llamado transformación. En 1928, el microbiólogo Frederick Griffith, que investigaba varias cepas de neumococo (Streptococcus |fqy| tke| xga| eta| mrp| mfi| gbl| vkk| lgz| nrd| wud| gsa| gsa| hfb| auq| iuz| jkc| bca| gmo| syn| ylk| bvx| mpn| gqy| rys| juh| hyf| ygw| ecd| ktu| cnd| vrq| cxn| qgv| ygu| afw| fqr| kvt| zga| scm| jzq| vsl| ewx| axa| jqv| ynu| rhu| kcy| cfd| tut|
