  1. Genetics Review

  2. State what each of these scientist discovered. • Frederick Griffith • Oswald Avery • Alfred Hershey & Martha Chase • Erwin Chargaff • Rosalind Franklin • James Watson and Francis Crick • George Beadle and Edward Tatum

  3. Before a new cell can be made DNA replication must occur. Define DNA replication and explain the process.

  4. All cells have a specific job to make proteins. This is a process involving many different molecules and enzymes. Describe the roll of each of the following molecules. • tRNA • snRNPs • Uracil • Chaperonin • exons

  5. Prokaryotes and eukaryotes are different in many ways besides the presences/absences of organelles. Describe 2 differences in the genetic makeup in eukaryotes and prokaryotes.

  6. Some viruses posses RNA as genetic makeup. When a virus, such as HIV, inserts RNA into a human Helper T cell it must also insert reverse transcriptase. Explain how scientist use reverse transcriptase in biotechnology today to benefit humans. List steps that must be taken to perform this process.

  7. Bacteria have a defense mechanism against viral DNA known as restriction enzymes. Explain how scientist use restriction enzymes in biotechnology today to solve crimes. Describe the use of sticky ends in your explanation.

  8. Bacteria reproduce asexually by binary fission. Describe three process of bacterial variation. • Pose an experiment for one of the process described above.

  9. Identify the cellular division process for step I and step II and briefly explain how each process occurs. Step I Step II

  10. In your laboratory, you use plasmids that carry the ampR gene to transform E. coli cells that lack this gene. You also prepare a second group of E. coli cells as a control to verify that E. coli will not grow on agar with ampicillin unless it is transformed, and that nothing in the procedure itself affects the survival of E. coli. The procedure is the same for both groups of cells except in step 2, where you add ampR plasmids to the experimental cells but not to the control cells. • Predict the growth of E. coli on each petri dish after a 24 hour incubation period. Justify your prediction. • Propose ONE specific improvement to each of the following parts of the experiment design and explain how the modification will affect the experiment. • Experimental control and environmental factor

  11. How do eukaryote regulate transcription? • How do prokaryotes regulate transcription?

  12. Mutation- A change in DNA • Point mutation • Frameshift Mutation Inherited Disorders- • Recessive Disorders • Dominant disorders • Sex Linked disorders Disorders related to chromosomal inheritance • Nondisjunction • Chromosomal disorders • Mitosis mutation vs Meiosis mutation?

  13. In 400 offspring, 100 offspring express the recessive disorder and 300 express the dominant disorder. What are the parent genotypes?

  14. A few more things to review… • Electrophoresis • Cell differentaion • Stem cells • Operons • Hox genes • Process of cloning in animals • Probability problems • Plasmid mappnig problems
