BIOL 133 CHAPTER 17 STUDY QUESTIONS | COMPREHENSIVE BIOLOGY STUDY
GUIDE, PRACTICE QUESTIONS & ANSWERS 2026/2027
Linkage analysis determines - correct answer ✔✔how close two genes are on the same chromosome by
recombination
Isolating all of the RNA out of an organism, subjecting it to reverse transcriptase, and then cloning all of
the resulting DNA into plasmids is the process of creating.
A. genomic libraries
B. cytogenetic maps
C. cDNA libraries
D. expresses sequence tags - correct answer ✔✔C. cDNA libraries
_____________hotspots can decrease the accuracy of linkage maps. - correct answer ✔✔Recombination
Three fish species are models for understanding different aspects of genes. Read the descriptions and
decide what sort of genetics each is used for. - correct answer ✔✔Three-spined stickleback-Stickleback
species have Variable structure of the bony vertebrae and different numbers of spines on the back
(Evolutionary genetics of Skeletal structures)
Danio rerio-the zebrafish common to the amateur aquaria. Many color morphs are available, they breed
readily, and embryos are transparent (Developmental genetics).
Takifugu rubripes-A poisonous marine pufferfist; has an unusually small genome compared to other
vertebrates but still carries all essential genes (Genome analysis).
In order to focus on only the expressed portions of DNA, what type of sequencing can be used? - correct
answer ✔✔whoe-exome sequencing
A change in the level of an individual protein in a diseased cell is known as a - correct answer
✔✔biomarker
Before cellular DNA can be subjected to gel electrophoresis, what needs to happen? - correct answer
✔✔Released and isolated
How can scientist tell how closely related two organisms are? - correct answer ✔✔The more genes they
share, the more similar
An individual may have a mutation that causes them to break down a drug much more quickly than
normal people. They were then provided with a higher dose, which was effective in treating the disease.
This is an example of - correct answer ✔✔pharmacogenomics
A species that is well studied so that we can learn more about the way we work is called a - correct
answer ✔✔model organism
