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 Chapters 16 and 17.

Heredity. is the transfer of characteristics anatomical as well as biochemical, from generation to generation. . The transmission of hereditary information from one generation to another takes place in the nucleus of the cell, . RNA. During protein synthesis certain specific regions of DNA (the genes) are copied into a polynucleotide of a chemically and functionally different type known as . ribo. nucleic acid.. RNA is a nucleic acid polymer consisting of nucleotide monomers that acts as a messenger between DNA and . .. 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. . As the enzyme moves along the template, the DNA duplex reforms.
