1. Summarize Griffith’s transformation experiments. 2. Describe how Avery’s experiment supplied evidence that DNA, and not protein, is the genetic material. 3. Describe the contributions of Hershey and Chase to the understanding that DNA is the genetic material. 4. Why did heat kill Griffith’s S bacteria? 5. What might Hershey and Chase have concluded if they had found 32P and 35S in the bacterial cells. 6. The first experiments that correctly identified the molecule that carries genetic information were performed by A. Oswald Avery. B. Alfred Hershey. C. Frederick Griffith. D. Martha Chase. 1. Describe the three parts of a DNA nucleotide. 2. Relate the base-pairing rules to the structure of DNA. 3. Describe the two pieces of information from other scientists that enabled James Watson and Francis Crick to discover the double-helical structure of DNA. 4. Explain why the two strands of the double helix are described as complementary. 5. Suppose a strand of DNA has the nucleotide sequence CCAGATTG. What is the nucleotide sequence of the complementary strand? 6. Which pattern shows how bases pair in complementary strands of DNA? A. A-C and T-G B. A-T and C-G C. A-G and T-C D. A-A and C-C 1. Explain the two roles that enzymes play in DNA replication as is illustrated in Figure 9 in this section. 2. Explain the relationship between DNA polymerases and mutations. 3. State the effect of multiple replication forks on the speed of replication in eukaryotes. 4. If a mutation occurs during the formation of an egg cell or sperm cell, is that mutation more significant or less significant than a mutation that occurs in a body cell? Explain. 5. How many DNA strands exist after one molecule of DNA has been replicated? A. 1 B. 2 C. 4 D. 8
lol. ... sheesh, and I thought at least you weren't lazy enough to type up the questions. I guess that proves you copied and pasted from a website or a CD or something, right?
1. He mixed stuff and saw that he got new stuff 2. By using the one stuff instead of the other 3. They localized stuff 4. Because it was too warm 5. Both thingies are injected 6. E and a custard pie 7. Left middle right
