Principles of Biology : End
of Semester Quiz Study Guide
We will take our End of Semster Quiz on Monday, Dec. 15. It is worth 50
points. About 25 points will cover genetics and DNA (Chapters 13-16)
and about 25 points will be from material before this section. I would
think studying the quiz guides and your quizzes would be the best way
to get started preparing for this quiz. I do not plan to use exactly
the same questions from quizzes on this quiz, but I tried to ask the
important stuff then and that is my aim now as well.
Reading: Chapters 1 - 17 in the text.
Questions for this quiz stricken from the last study guide:
1) What is an exon? an
intron?
2) What is the
"spliceosome?" What is its function?
3) How do new genes come
about? Give an example?
4) What is the role of
mutation in evolution?
and now new questions:
5) What is main difference in control strategies between prokaryotes
and (especially) mulitcellular eukaryotes.
6) What is the lac operon and how does it work? (see Figure 16.4 page
309)
7) What are some of the mechanisms whereby eukaryotes can control gene
expression? (see figure 16.18 page 320)
8) What is recombinant DNA?
9) What are restriction endonucleases?
10) What role does gel electrophoresis play in biotechnology?
11) What is a clone? What is "molecular cloning" or "gene cloning?"
12) What is a vector? What is the difference between plasmid vectors
and phage vectors?
13) How, in general terms, are these vectors used in genetic
engineering?
14) What is "reverse transcriptase?" In what organisms was it first
found? What does it do to the Central Dogma?
15) How can genetic engineering be used to create vaccines?
16) What is "golden rice?" How does it differ from regular rice?
17) What is "biopharming?" Give an example.
18) What are the concerns about genetically modified crops and animals?
19) How do these concerns relate to the overall evolution of humans as
organisms on the planet?
