AP Bio - Heredity 1. (Short answer). In what way does pre-RNA differ from mRNA? 2. (Short answer). What is ncRNA and what is its role? 1 3. (long answer). Explain the process by which DNA makes proteins. 2 4. (long) By using techniques of genetic engineering, scientists are able to learn more about the human genome and to use these techniques for the betterment of mankind. Describe those techniques below, and explain how each contributes to our understanding of the genome or for what practical purpose it can be used. a. PCR b. RFLP analysis c. Gene cloning 3 5. (long). All humans are genetically identical. However, every person has a unique DNA fingerprint. Explain this contraction. 6. Describe two events that are common to both mitosis and meiosis that ensure the resulting daughter cells inherit the appropriate number of chromosomes. 4 7. The genetic composition of daughter cells produced by mitosis differs from that of the daughter cells of meiosis. Describe two features of the cell division process that lead to these differences. 5
