1. Modern forensic biotechnology labs use sophisticated machines to analyze ________, such as D16, and to determine the number of specific genetic repeats in the samples.
A) RFLPs
B) primers
C) PCRs
D) STRs
2. Imagine that it is 1965 and the bacterium Thermus aquaticus has not yet been discovered. As a geneticist interested in forensics applications, you are attempting to develop a gene-amplifying technique similar to PCR. In a test tube, you place a DNA sample, free nucleotides, human DNA polymerase, and the appropriate primers for the DNA sequence being analyzed. You first heat the sample to 90°C, then cool it to 50°C, and then reheat it to 70°C.
Based on this scenario and your knowledge of how modern PCR works, the result of these procedures will be:
A) successful copying of the DNA, because it follows modern PCR procedures almost perfectly.
B) unsuccessful, because the enzyme will denature during the second step (cooling).
C) unsuccessful, because the enzyme will denature during the first step (heating).
D) unsuccessful, because the enzyme will denature during the third step (reheating).
3. Which transgenic organism is used to produce BioSteel® fibers for medical and microelectronic applications?
A) Escherichia coli
B) Thermus Aquaticus
C) goats
4. Which of the following is NOT a valid difference between traditional and modern forms of biotechnology?
A) Modern biotechnology can isolate and manipulate individual genes.
B) Traditional biotechnology cannot produce entirely new genes in one step.
C) Modern forms of biotechnology are slower than traditional forms of biotechnology.
D) Traditional biotechnology is almost always limited to genetic recombination between individuals of one species or two closely related species.
5. Which of the following can be used to detect genetic disorders?
A) arrays of DNA probes only
B) RFLPs and DNA probe arrays only
C) restriction fragment length polymorphisms (RFLPs) only
D) single tandem repeats (STRs) only
Answers to any of these questions will be greatly appreciated. Thanks in advance to everyone!
