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






2. Selects for the middle and against the extremes






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






4. Sexual partners chosen based on some characteristics






5. 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






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






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






8. Sometimes different species share common ancestors






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






10. Capable of asexual reproduction; most are not






11. Way more offspring are produced than by sexual reproduction






12. Cells that can turn into other cells






13. A widely accepted idea with lots of evidence






14. One extreme is selected over the other






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






16. The change in a populations genetics






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






18. The idea that characteristics can enhance an organisms survival






19. Directional selection - Disruptive selection - Stabalizing






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






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






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






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






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






25. A subset of a population colonizes a new area






26. 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






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






28. 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






29. Selects for the extremes and against the middle






30. Humans selecting certain traits in domestic organisms






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






32. 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






33. The organism with the most advantageous traits will survive






34. Form of reproduction more used because it creates Variation






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

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






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






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






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






40. Differences in appearances between the sexes






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






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






43. Forms that show how an organisms anatomy change over time






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






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






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






47. Direct competition for mates with the same sex






48. Change in alleles due to random chance






49. Results in a genetically identical inidvidual






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