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.

7. Recombinant DNA may enable __________ to determine the likelihood of a praticular genetic disease long before the appearance of symptoms associated with the disease;early detection may allow intervention before the occurrence of irreversible damage.






8. Can be inserted into plants or animals to produce organisms that are better adapted to their environments - has been shown to cause improvements in crops by improving things such as drought resistance and has conveyed immunity to those consuming them






9. 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.






10. Profile established by analysis of multiple markers provides unique characteristic of individual whose DNA is presented;

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






13. 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






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






16. DNA fingerprinting of specimens that contain only minute amounts of DNA or even old specimens that may not be suitable for other test methods






17. Can revert to anaerobic fermentation in the event they have exhausted their oxygen supply - creating lactic acid






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






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






20. The actual sequence of nucleotides that make up the DNA molecule; we have due to lab techniques in genetic engineering - the ability to creat a DNA fingerprint ( DNA type or DNA profile) that is unique identifying characteristic of an individual






21. The ability to produce recombinant proteins in bacteria and yeasts reather than isolating protein from animals or humans






22. Involves manipulation of an organism's genome - Used in conjunction with biotechnology - which involves practical use of an organism's biochemical and metabolic pathways for the production of food products - chemicals - drugs andother products






23. 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

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






26. 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






27. Ethyl alcohol






28. 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






29. Are observable variations in DNA which help establish a profile

31. Incompatible DNA of bacteriophages and plasmids






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






33. Corn mash whiskey - is clear after distillation - the aging process while in an oak barrel for years - is responsible for the golden color and distinct taste of bourbon (or Jack Daniels Tennessee whiskey)






34. Fermented and distilled corn mash - the state of Kentucky holds the patent on the word bourbon in reference to corn mash whiskey. Jack Daniels - produced in Tennessee is bourbon but NOT CALLED bourbon due to this patent
