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






2. Cells that can turn into other cells






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






4. Theory of a stable - nonevolving population in which frequency of alleles do not change; only occurs in large - isolated populations with random mating - and no natural selection or mutations






5. Selects for the extremes and against the middle






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






7. Sexual partners chosen based on some characteristics






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






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






10. 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






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






12. Form of reproduction more used because it creates Variation






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






14. Humans selecting certain traits in domestic organisms






15. Way more offspring are produced than by sexual reproduction






16. 1.edits existing variation by using the material it has(variation that exists in population/ no new traits created by natural selection) 2. Has historical constraints(change in old structures) 3. Adaptations are compromises (good for one thing - bad






17. Selects for the middle and against the extremes






18. Related organisms have similar development plans






19. Sometimes different species share common ancestors






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






21. Directional selection - Disruptive selection - Stabalizing






22. Capable of asexual reproduction; most are not






23. A group of interbreeding organisms living in the same place at the same time






24. Taking good genes to replace bad genes; almost never works; has unintended side effects; sometimes just doesn't work; protein becomes degraded - etc






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






26. Differences in appearances between the sexes






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






28. One extreme is selected over the other






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






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






31. Came up with the term catastrophism(sudden events that lead to extinction - but not in todays time)






32. Results in a genetically identical inidvidual






33. Mate choice; one sex chooses their mate






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






35. The idea that characteristics can enhance an organisms survival






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






37. A subset of a population colonizes a new area






38. 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






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






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






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






42. Change in alleles due to random chance






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






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






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






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


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






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






49. Direct competition for mates with the same sex






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