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






2. Derived from sugar cane juice - is a primary alcoholic product of the caribbean islands - can be purchased in several different concentrations






3. Enabling the large- scale production of life- saving or life- altering hormones and enzymes of human origin






4. Derived from potatos is the most widely marketed and consumed alcoholic beverage






5. Although the availability of HGH was limited at best - demand exceeding the opportunity of supply - the potential transmission of infectious agents such as the prion associated with Creutzfedt- Jacob disease was life threatening to the individual rec






6. Used in industry - agriculture - food sciences and environmental protection. Some utilize genetic engineering techniques to achieve a desired outcome or rely on natu4ral biochemical and metabolic activities of organisms






7. 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






8. The process of introducing foreign genes into a cloning host organism






9. Enzyme required for conversion of inactive protein plasminogen to its active form plasmin; is used to dissolve clots associated with myocardial and cerebral infarctions - availablity of tPA from human origin is limitied and not sufficient to meet the






10. A good recombinant vector must be capable of carrying a significant fragment of DNA and readily accept it






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






12. Once the specific functional protein will be synthesized - the availbility of the protein will eliminate the disease condition






13. Degree of uniqueness is directly proportional to the prevalence of particular markers in comparison population; use of multiple markers allow significant increase in actual uniqueness of profile established






14. Which encodes for a particular protein product into the genome of appropriate host organism transforms the host organism into a production plant for the protein that is the genetic expression of a particular sequence - then - by means of routine bioc






15. Use of an organism's biochemical processes to produce a needed product - These processes have been greatly enhanced by use of recombinant DNA which allows organisms to be genetically modified to accomplish tasks that were previously not possible






16. Is a lab technique used to separate various sized restriction fragments






17. Caused by a lack of adequate clotting factor VIII;






18. Plasmids and bacteriophages






19. Almost 6000 yrs ago in wine and bread making - involves practical application of microorganisms in manufacturing products or carrying out a particular decomposition - most involve the actions of bacteria - molds - yeasts adn algae that have been sele






20. yeasts ferment carbs in fruits & grains anaerobically resulting in producing ethyl alcohol






21. 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.






22. Ethyl alcohol






23. 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






24. Caused by a lack of adequate insulin production - once treated using insulin derived from animals






25. Genetic Engineering is based on the ability to manipulate DNA by using a variety of ___________;allow DNA to cut precisely determined points along each strand - to be separated according to size of fragments and to be sequenced to determine exact com

28. Lactobacillus Sanfrancisco






29. Anaerobic fermentation in skeletal muscles produces






30. Pieces of DNA produced by endonucleases - when in the laboratory - endonucleases are used to cleave DNA at desired sites - allowing them to be seperated by Gel Electrophoresis by size - then allowing the nucleotide sequences to be isolated and ident






31. 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






32. Involves removal of a selected gene from on organism (genetic donor) followed by its propagation in a different organism (cloning host)






33. Saccharomyctes cervisiae


34. 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
