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. 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

17. Many individuals recieving treatment for their Hemophilia A through blood transfusions contracted the HIV virus - through the donated plasma






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






19. 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






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






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






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






23. 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






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






25. 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






26. Is essential in the process of clot dissolution associated with myocardial and cerebral infarctions
