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.

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






14. 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)






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






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






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






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






19. 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

21. 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






22. 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






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






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