textbook found the basic structure of nucleotides
-
textbook he did an expirement that showed how a smooth stand of pneumoniae could be transformed into a rough stand but a rough stain couldn't be transformed back into a smooth form
-
textbook He did more expirements with pneumoniae. He tested what molecule allowed the rough pneumoniae back to the smooth. He found that when a rough strain was intreduced to the DNA of a smooth strain it transformed into the smooth strain
