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. 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






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. 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






10. 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






11. Insertion of particular recombinant DNA sequences that encode missing or dysfunctional proteins

16. Gel electrophoresis is a process based on migration of negatively charged DNA fragments through a gel - toward a positive electrode






17. 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






18. 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






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. 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.






21. Fast growth rate - ability to be grown in large quantities using ordinary culture methods - Nonpathogenic -Genome that is well- delineated (mapped) - capable of accepting plasmids or bacteriophage vectors - maintains foreign genes through multiple ge






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






23. 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






24. 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
