Description

STUDY GUIDE FOR EXAM #1 BIOLOGY 151 Preliminary Version. This study guide is meant to help you focus your studying efforts. Please realize that it is not comprehensive and does not necessarily include everything that you might see on the exam. Anything that was discussed in class, assigned readings, learning objectives, or MasteringBiology is eligible for inclusion on the exam. However, if you know the material listed below thoroughly and are able to apply your knowledge, then you should be able to do quite well on the exam. The exam will consist of 40 multiple-choice questions. I generally recommend that you at least try reading the chapters in your book (focusing on those topics that we cover in class) just as an opportunity to view the main concepts from a perspective that may be different from how they are presented in class. However, please realize that I try to write exam questions according to how the material was presented in class. I would NOT recommend that you spend a lot of time trying to memorize your textbook! Instead, focus your time learning, understanding, and being able to apply information from your class material. We will spend class time on Tuesday (1/30) for review— please come with questions!

The exam will cover chapters 13-18. Please bring a No. 2 pencil and your ID No. to the exam. For exam 1, you should be able to: 1. Explain the difference between homozygous and heterozygous. 2. Use a punnett square to figure out expected phenotypic and genotypic ratios in successive generations (with both monohybrid and dihybrid crosses). You should also be able to do this with the A, B, O blood types. 3. Differentiate between incomplete dominance, codominance, and gene-gene interactions. 4. Explain the process of DNA replication, including the roles of various enzymes. 5. Explain the significance of telomeres and telomerase. 6. Explain the experiments that support DNA (and not proteins or RNA) as the genetic material. 7. Explain the Meselson-Stahl experiment and be able to predict results and interpret results. 8. Explain the process of transcription including the steps involved in initiation, elongation, and termination as well as the roles of promoters and transcription factors. 9. Explain how the primary mRNA transcript is processed before it is translated. 10. Explain the relationship between DNA, codon, anticodon, and amino acids. 11. Identify the sequence of amino acids in a protein if given a DNA sequence and a table with the genetic code. 12. Explain the role of mRNA, tRNA, and ribosomes during translation. 13. Explain how the lac operon works in the presence/absence of lactose including the role of each of the following: repressor protein, promoter, operator, lac z, lac y. 14. Don't forget the "end of chapter" questions that I assign with each chapter. 15. You should also be able to answer questions based on the ALAs completed in class. 16. Be sure to review the MasteringBiology and RAT questions as well....
