Study Guide 4
Concepts of Biology - BIOL 111
This study guide covers chapter 11 in your book.
1. The lecture slides used in class may also be found on the class website.
2. Some advice about using these study guides. Don’t just answer the questions and
call it good. Print out a second (or even a third) copy of the SG and answer the
questions from memory.
3. Review the old study guides. You do not get to forget what you have already
learned! At least 25% of the quiz will be over material from previous study
guides.
4. Describe Griffith’s experiment.
5. Describe Avery, McCarty and MacLoed’s experiments.
6. What is DNA? What are the monomers of DNA and how are the arranged in the
cell? DNA is composed of what sugar?
7. Draw a cartoon of the three major components of a nucleotide.
8. What does it mean to say that DNA strands are antiparallel, and complementary,
and form a double helix?
9. Name the DNA bases/nucleotides and their abbreviations.
10. How are DNA, genes, chromosomes and genomes related?
11. What is an exon and an intron?
12. What is supercoiling?
13. What is the central dogma?
14. What enzyme is responsible for replicating DNA?
15. Define Semi-conservative replication.
16. What are the differences between RNA and DNA?
17. What enzyme is involved in RNA synthesis?
18. What direction does DNA and RNA synthesis occur in?
19. Where does transcription occur in eukaryotes?
20. What RNAs are involved in translation and what are their roles?
21. Where does translation occur?
22. What are the effects of mutations?
23. Draw or describe the structure of a tRNA.
24. Why is the genetic code degenerate?
25. What is the wobble effect?
26. Describe the steps in translation.
