Genetic Engineering Technology

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. 2 -00-5 -000 base pairs






2. Expensive - have short life spans (short telomeres) - cloned from previous animals age






3. RFLP and PCR






4. Induced pluripotent stem cells - nuclear reprogrammed somatic cells






5. Can't be used if bacteria does not have the same post- translational modifications as eukaryotes --- no glycosylation - Can use bacteria to produce eukaryotic proteins only if the protein does not require any post- translational modifications. (Or un






6. Centers for Disease Control and Prevention - protects public health and safety - provides information about health decisions and promotes health programs - works with disease - food- borne pathogens - occupational safety.






7. Scaffolds - cells - cultivation

8. To create or modulate tissue to replace or augment diseased or damaged tissue






9. Antigens are foreign substances that stimulate an immune response






10. The nucleotide sequences are present in the initial mRNA transcript but are excised prior to translation






11. Laboratory technique uses a DNA polymerase from bacteria that grow in geysers - Allows for the exponential increase in the synthesis of specific segments of DNA






12. Responsible for the control of pesticides - herbicides - etc






13. Only 1/100th of DNA differs from person to person






14. Is produced by a hybridoma (the fusion of a mature b- cell and an 'immortal' myeloma cancer cell - Is a single type of antibody that cross - reacts to only one target - one portion of the antigen against which it was made - Are generally much more sp






15. Cell consistency - Scaffold design and prep - Bioreactor design - Producing in the right size - Time of production - Clinical use - Regulatory approval - Ethical questions






16. The target antigen (protein) for the vaccine is more easily selected and the vaccines can be generated much faster in microbes than in eggs






17. Food and Drug Administration - in charge of processed foods and medication - oversees the lab practices - phase testing of drugs - drug - food items - cosmetics






18. Plasmids that are successfully engineered are white - If the gene is blue it is not effected - White colonies are inserted into the clone of DNA on Bgal site - Allows for detection of successful ligation (in vector- based gene cloning)






19. Embryo twinning (split embyos in half) - cloned from adult DNA






20. National Institute of Health - foremost medical research center - makes important health discoveries






21. Done after treatment has been marketed and used - studied in various populations






22. Genes allow for selection and identification of bacteria that has been modified (undergone recombination)






23. Must be able to define its specific utility (must know exactly what it does... specifically) - show its substantial utility (real world use) - meet the credible utility requirement (be backed by sound science) - and not be similar to something else (






24. A problem with gene therapy






25. Short reproductive cycles - similar physiology to humans - sufficient database of knowledge about the organisms genetics - don't have dorsal fins and rows of large sharp teeth - they produce a relatively large number of offspring






26. Greatest good for the greatest number






27. It sequentially breaks down toxic compounds - eventually to water and CO2






28. Responsible for growing and farming practices






29. Not obvious - Have a use - be novel






30. Advancement and regulation of agriculture - pests - plants and vet biologics - growing and farming practices






31. Tested on those with disease - 100-300 EFFICACY






32. DNA copy of an mRNA molecule expressed in a cell






33. Short stretched of DNA with single base pair changes (wildtype) - Short length allows distinguishing which allele is present - Allows the probe to stay attached to the target DNA - Perfectly matched will cause a signal






34. US Patent and Trademark Office - only one required by the constitution - oversees patenting






35. Pieces of DNA that can accept carry and replicate other pieces of DNA






36. Injection into the organism






37. Genetically type biological tissue - identify matching pairs (that cause undesirable traits in offspring) - and can show these traits early in development - check for curly calf syndrome - water head - fawn calf syndrome - dwarfism - dsytocia - and c






38. Human embryonic stem cells - from embryos left over or created - have the ability to undergo differentiation - pluripotent






39. Protective cold- induced proteins from fish that live in very cold climates






40. Used in fingerprinting - Less DNA and can be slightly degraded - Extremely sensitive to contaminating DNA






41. Composition of matter (chemical union) - Method - Article of Manufacture - Machine






42. Responsible for drug - food items - and cosmetics






43. The act that started the clean up of sites that had hazardous substances






44. Cut small discs of leaf - culture in genetically modified agrobacter - Leaf discs are treated with hormones






45. Chemically - Mechanically - New ways to take from levis






46. Prevent crops from freezing (ice-) - slow the breakdown of food (tomatoes) - create pesticides to stop infestations






47. Recognize and bind to the antigen - Each individual cell has ONE antibody - First exposure to a foreign protein: B- cells cross - react to the protein - proliferate - and produce antibodies against the protein






48. Skin and cartilage






49. Informed consent is required: must know the risks (not actually receiving the drug)






50. Responsible for the standard of treatment for laboratory animals
