Nucleic acids are one of the major organic biomolecules.. Chapter 12 DNA & RNA I.DNA A. Griffith & Transformation Frederick Griffith was trying to figure out how bacteria made people sick-how they cause a certain type of pneumonia. He isolated 2 strains(types) from mice-both cultured well,but only one caused pneumonia.The culture of the disease causing bacteria were __________________colonies while the other was rough Transformation. 1928- . Frederick Griffith . was trying to figure out how bacteria made people sick. Pneumonia. Cause of pneumonia was not a chemical poison released by disease causing bacteria. The heat killed bacteria had passed their disease-causing ability to the harmless strain. .. The length of the transcription bubble is about 12 to 14 . bp. , but the length of the RNA–DNA hybrid within the bubble is only 8 to 9 . bp. .
