Recombinant Dna Technology

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. A circular piece of DNA in bacteria where the gene is placed in Recom. DNA technology






2. Can make large quantities of product; infection free; less expensive than a natural source






3. A widely accepted idea with lots of evidence






4. Mutation - Natural selection - Genetic drift - Bottleneck effect - Founder effect - Gene flow - and Mate choice/non - random mating






5. Cuts DNA in specific sites; the fragments created are usually predictable






6. The change in a populations genetics






7. Related organisms have similar development plans






8. Direct competition for mates with the same sex






9. Results in a genetically identical inidvidual






10. Form of reproduction more used because it creates Variation






11. The more common a trait becomes the more likely it will be selected against






12. The screening of embryos for genetic disorders; done in In Vitro fertilization(fertilization in a petri dish); PGD removes one cell from the embryo and screens it genetically; embryos with disorders are discarded - ones without are kept and implanted






13. Traits that are neither advantageous nor disadvantageous; there is no selection






14. Mate choice; one sex chooses their mate






15. Cells that can become any cell in the body; found in the embryo






16. A process to help separate DNA fragments using an electrical current; helps to compare DNA samples by fragment pattern






17. Takes the gene from a needed product - puts it into another organism (usually bacteria) and it will make duplicates of the product






18. Closely related organisms have more similar DNA sequences and protein structures






19. Comparing an unknown sample of DNA to a known sample by using Gel Electrophoresis; used in crime scenes - paternity tests - and remains identification






20. Pharmaceutical animals; cloned animals used ot produce products for humans

21. Selection fro or against environment; leads to evolution only if variation has genetic components






22. Distribution of organisms related to evolution; different organisms play the same roles on different continents; island organisms resemble organisms on nearby mainland






23. The movement of genes between two populations e.g. migration - immigration






24. Set sail on the HMS Beagle to travel the islands and areas for signs of evolution; First book written in 1839 'voyage of the Beagle'; Second book published in 1859 'The Origin of Species by means of Natural Selection






25. Selects for the extremes and against the middle






26. Believed that change was gradual;Gradualism(the mechanisms of the world - then - are the same today)






27. The organism with the most advantageous traits will survive






28. One extreme is selected over the other






29. When a population becomes smaller and a few individuals survive the event






30. All species on earth are fixed; no changes - no new species - no extinction






31. Change in alleles due to random chance






32. The idea that characteristics can enhance an organisms survival






33. Scientific explanation of how life changes over time - science is based off of evidence - science is obtained with observation and testing - science is always open to question






34. Humans selecting certain traits in domestic organisms






35. Cells that can become only a few different types of cells; mostly adult stem cells; found in bone marrow - the skin epidermis - etc; can sometimes be turned into Totipotent stem cells






36. Change in the DNA sequence of an individual; the only true way to get a new allele; the source of all heritable variation






37. Recessive traits persistent to a certain population; recessive alleles hide from selection






38. Heterozygous chromosomes have an affect on an individuals genetics/alleles






39. An accumulation of genetic charges over a certain amount of time






40. Results in a tissue or an organ that is identical to the DNA donor






41. Came up with the term Uniformitarianism(mechanisms for change in the past still occur today; believed at first there was no evolution






42. Directional selection - Disruptive selection - Stabalizing






43. Number of offspring in the next generation; your contribution to the gene pool






44. Invented the binomial method(naming of species); also believed that life was fixed






45. The process of sperm sorting; separating the male sperm from the female sperm; difference told by swimming speed; boy sperm swim faster than girl sperm; Theory might have flaws in it though - only works 50% of the time






46. Choosing the sperm/egg/embryo that will produce the desired child depending on DNA(genes)






47. Subset of natural selection that increases the likelihood of mating specifically






48. Sometimes different species share common ancestors






49. Another method designed to sort female sperm form male sperm; goes by size of sperm; females are bigger than male sperm






50. In related organisms the underlying anatomy is similar even when the function is different
