MODULE 1
1. The module discusses how the domestication of dogs from wolves may have gradually taken
place. For instance, friendly wolves approached humans for food and companionship, and the
humans realized that they enjoyed the wolves' company and could use them in their hunting and
gathering. Can you think of another example of an evolutionary process that occurred that would
have given humans a distinct advantage?
- Humans becoming bipedal so they are upright and have a better view in order to avoid
predators
2. Early theories proposed that the fertilized egg contained a tiny human in a form called the
__________.:
Homunculus
3. Where were restriction enzymes first discovered? How are they useful in genetics research and
biotechnology?
- Discovered within bacteria cutting and inactivating the DNA of invading viruses
- Useful in research to cut/fragment DNA in order to isolate genes
4. Epigenesis:
The concept that a fertilized egg undergoes developmental events that lead to the
formation of a human.
5. The traits that Mendel referred to as "units of heredity" are presently known as _______.:
Genes
6. Preformation:
The fertilized egg contains a complete miniature adult (homonculus)
,2|Page
7. Who discovered double helix DNA structure?
Watson and Crick
8. True or False: Avery, MacLeod, and McCarty showed that DNA was responsible for carrying
genetic material in bacteria.
True
9. True or False: A mutation within a gene always results in the loss of that gene.
False. Genetic mutations result in different alleles, resulting in a different version of the
"normal" gene.
10. Humans have a haploid number of:
23
11. Humans have a diploid number of:
46
12. Why is it important to choose an animal research model carefully?
- Substantial investment of time and money in research
- Animals for genetic research are chosen for a short life span, ease of breeding, low
expense, and the ability to study them easily.
13. Who introduced cell theory?
Mathias Schledein Theodor Schwann
14. What did Mathias and Schledein propose?
That all living organisms were composed of organized structures called cells and that these
cells were derived from identical precursor cells
,3|Page
15. Who theorized natural selection?
Charles Darwin
16. Who used pea plants to model how traits are inherited from generation to generation>:
Gregor Mendel
17. What does Mendel's experiment explain?
Basic foundations of trait transmission
18. True or False: All genetic disorders will show a phenotype early in life, if not at birth.
False. Some genetic disorders manifest later in life.
19. Darwin's Theory of Natural Selection:
Pressures in the environment select for the organism most fit to survive and reproduce
20. What animal can be humanized?
The mouse
21. Benefits of using fruit flies as research subjects:
- Inexpensive
- Short life span
22. What is unique about the zebrafish?
Transparent egg and embryo
23. What has a simple nervous system that is easy to research?
, 4|Page
Worms
24. How does preformation differ from epigenesis?
Preformation postulated that a fertilized egg contained a miniaturized version of a tiny
human, called a homunculus. Epigenesis directly contradicted that theory by stating that a
fertilized egg undergoes a series of developmental events that eventually form a human.
25. Transgenic:
Organism whose genome has been altered to contain one or more genes from another
organism or species
26. What type of plants did Gregor Mendel use in his famous experiments?
- Pea plants
27. The chromosomal theory of inheritance states that:
Genes, contributed from each parent, are carried on chromosomes.
28. True or False: Nucleotides are the basic building blocks that make up DNA.
True
29. Explain how the use of biotechnology has contributed to modern agriculture.
Transgenic plants have been engineered to resist insects and harsh environments, grow
bigger and more prolifically, or to enhance nutrition.
30. What is theory of spontaneous generation?
Living things can spontaneously generate from non-living things.
