Download FileIdentifying the Substance of Genes. The instructions that cause a single cell to develop into an oak tree must be written into the DNA of the organism Lesson Overview Identifying the Substance of Genes Bacterial Transformation To truly understand genetics, scientists realized they had to discover the chemical nature of the gene. Griffith's experiment showed that Lesson Overview to Answer That Question, the First Thing You Need to Identifying the Know Is What Genes Are Made Of AP® Biology from Gene to Protein— a Historical find out, he ran the series of experiments shown in Figure–First, Griffith took a culture of the S strain, heated the cells to kill them, then injected the heat-killed bacteria into laboratory mice. Explain why you drew your sketch the way you did. When the cell splits open, hundreds of new viruses burst out The drawing below shows half of a DNA molecule. genetic material found in genes—not just in viruses and bacteria, but in all living cells. If the molecule that carries genetic information could be identified, it might be possible to understand how genes control the inherited characteristics of living things A typical bacteriophage is shown. Identifying the Substance Use an oak tree to give an example of each function. The Role of DNA The DNA that makes up genes must be capable of storing, copying, and chpdf. Apply the Big ideaComplete this table to show how the structure of the DNA molecule allows it to perform each essential function. The DNA that makes up genes controls development and characteristics of different kinds of organisms. Function Lesson: Discovery of DNA. Key Questions: What role did bacterial viruses play in identifying genetic material? The mice sur-vived, suggesting that the cause of pneumonia was not a toxin from these disease-causing bacteria. By observing bacterial transformation, Avery and other scientists discovered that the nucleic acid DNA stores Identifying the Substance of Genes. The viral genes act to produce many new bacteriophages, which gradually destroy the bacterium. What is the role of DNA in Identifying the Substance of GeneFree download as Word Doc.doc /.docx), PDF File.pdf), Text File.txt) or read online for free. When a bacteriophage enters a bacterium, it attaches to the surface of the bacterial cell and injects its genetic information into it. Fill in the appropriate letters for the other half.
