In the middle of the 1900’s scientists were asking questions about genes.. Where do we find DNA?. How do crime scene investigators use DNA to solve crimes? . NUCLEIC ACIDS. Flow of biological information: . DNA . RNA. protein . trait. DNA . deoxyribonucleic acid. 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 Gene Expression. When a cell “reads” the DNA, it doesn’t directly say for example blue eyes.. . What the DNA actually says is what types of proteins to make, when to make them, & how much of them to make.. .. 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. TRIzol. purification: precipitate out everything BUT the RNA. Two common methods for separation of RNA from DNA. Selective precipitation of RNA using Lithium Chloride (LiCl). Extraction with phenol buffered at an .
