Chapter 7 Biotechnology: How Do We Use What We Know about Life? 1. “Designer babies” and “gene therapy” can be considered forms of biotechnology because: a. both involve artificial manipulation of virus particles b. both use tools and techniques for manipulating genetic material in organisms c. both use counseling therapy to guide the decision making process d. both can result in non-living forms created from living organisms e. both use DNA technology for industrial purposes Ans: b 2. In the 1960’s the flow of cell functioning information in prokaryotic cells was identified as a. transcription of DNA genetic information –> translation of mRNA message -> formation of proteins necessary for cell function b. replication of DNA genetic information -> cell division - > cell division -> functioning cell c. translation of mRNA message in nucleus to DNA genetic information which directs functioning of cell d. formation of proteins necessary for cell function -> assembly of DNA genetic code e. transfer of DNA genetic information to alternate cells via plasmids which direct function of cell Ans: a 3. All of the following contribute to the use of microbes or prokaryotic cells to study and manipulate eukaryotic DNA EXCEPT: a. microbes are small, inexpensive to maintain, and easy to house b. microbes are quick to multiply in the laboratory c. microbes can grow great quantities of a single DNA directed substance d. the prokaryotic chromosome is simple and therefore easy to insert into eukaryotic DNA e. microbe mutation provides the variation necessary for eukaryotic DNA cloning Ans: e 4. All of the following can be used to describe a cloning vector EXCEPT a. a cloning vector is a genetic hitchhiker b. a cloning vector is a genetically engineered plasmid c. virus can act as a cloning vector 83

Chapter 7 d. a cloning vector is an artificial lipid that can be used to control cell replication e. a cloning vector is a vehicle that inserts a fragment of foreign DNA into the genome of a host cell Ans: d 5. The technology of genetic engineering has revolutionized the pharmaceutical industry through a. the ability to make generic drugs b. the ability to use bovine proteins to treat disease c. the ability to use bacteria cultures to produce mass quantities of a protein d. the ability to use porcine proteins to treat disease e. the ability to produce vaccine from viruses Ans: c 6. Restriction enzymes or restriction endonucleases act as molecular a. super glue b. scissors c. erasers d. scribes e. magnifiers Ans: b 7. “Sticky ends” is a term that describes a. the DNA that is left behind after bacteria have been removed from a culture plate b. the unpaired DNA bases after the DNA has been exposed to a restriction enzyme c. the bacterial strain that ends with the same initials as its corresponding restriction enzyme d. the last sequence of a DNA strand that codes for STOP e. the affinity of a restriction enzyme for a particular sequence on the DNA strand Ans:
