Genetic Engineering Biotechnology

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Recombinant DNA may be inserted into ________ to produce organisms that are better adapted to their environments - may not be disease or drought tolerant - may provide more nutritional properties - may be easier to grow - or may even convey immunity

7. To deliberately remove genetic material from one organism - and combine it with the genetic material of another






8. Gene therapy involves insertion of particular recombinant DNA sequences that encode for ___________; used increasingly to replace missing or mutated genes to correct inherited defects






9. After the actual size of individual fragments are determined - the nucleotide sequence which has been isolated and identified - can be inserted into an acceptable cloning host through the process of transfection






10. Was a 4 yr old girl - in 1990 suffering from severe immunodeficiency disease caused by lack of enzyme adenosine deaminase (ADA). Researchers at the National Institutes of Health - transfused her own blood cells that had been engineered to contain the






11. Caused by a lack of adequate Human Growth Hormone (HGH); once treated by harvesting HGH from the pituitary glands of human cadavers






12. Limited availablity of the essential - missing or deficient hormone - which can be aided by pharmaceutical companies use of recombinant DNA technology.






13. A lack of an essential hormone causes the disease and treatment involves replacing the missing hormone






14. Identification of the gene responsible for the defective or absent protein - identification - isolation - cloning of the normal gene and transfection into the cells of the individual with the disease.






15. Actions of microbial enzymes that break down flour proteins ( gluten) and give dough its elasticity






16. A faulty gene in humans suffering from a disease which is due to the lack of a protein or the presence of a defective protein is corrected or reparied; inherent benefit is to permanently cure physiological dysfunction by repairing a genetic defect






17. Are bacterial enzymes that recognize foreign DNA and are capable of breaking the bonds between adjacent nucleotides; each has a specific nucleotide sequence as its target

20. Use recombinant DNA technology to synthesize products that cannot be manufactured by other methods - or cannot be manufactured as efficiently or effectively by other methods






21. Migration is due to attraction of opposite charges - smaller fragments move faster than larger ones - which allows the restriction fragments to be not just seperated but isolated and identified
