Chapter 12 Vocab Assignment Use your textbook to define the following vocabulary words, found in chapter 12. Try to find the definition in the context of the chapter rather than going straight to the glossary! Transformation DNA Polymerase Translation Bacteriophage Messenger RNA Anticodon Nucleotide Ribosomal RNA Mutation Base pairing Transfer RNA Point Mutation Chromatin Transcription Frameshift Mutation Histone RNA Polymerase Replication Codon Then, answer the following questions, while reading chapter 12. These questions should be answered in your vocab notebook. Chapter 12-1 and 12-2 Reading Questions. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Describe the experiments of Frederick Griffith, including the date of his work and his nationality. What was Griffith’s primary discovery? Describe the experiments of Oswald Avery, including date of his work and his nationality. What was Avery’s primary discovery? Describe the experiments of Alfred Hershey and Martha Chase, including date of their work and their nationality. What was Hershey and Chase’s primary discovery? What are the four nucleotides that make up DNA? How do these nucleotides pair in DNA? What is a replication fork? What role does DNA Polymerase play in DNA replication? Draw a diagram of a piece of DNA undergoing replication. (Check out Figure 12-11!) Label the replication fork, and show the complimentary new strand of DNA that would be produced, using the letters A, C, G, T and what you know about how they pair with each other. Chapter 12-3 and 12-4 Reading Questions. 1. 2. 3. 4. 5. These should be complete by 2/25 and 2/26. These should be complete by 3/2 and 3/3. What are the three types of RNA and what are their jobs? What happens during transcription? What happens during translation? Describe the three main differences between RNA and DNA. Use Figure 12-17 to determine the amino acid sequence based on the following messenger RNA strand codes: UGGCAGUGC OVER 6. 7. 8. 9. 10. What is a gene mutation? What is a chromosomal mutation? What is a point mutation? What are two kinds of frameshift mutations? What are four types of chromosomal mutations? This assignment is due March 2nd and March 3rd!
