Test your basic knowledge |

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. Way more offspring are produced than by sexual reproduction






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






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






4. Humans selecting certain traits in domestic organisms






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






6. Selects for the middle and against the extremes






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

8. 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






9. A subset of a population colonizes a new area






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






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






12. A widely accepted idea with lots of evidence






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






14. 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






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






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






17. Selects for the extremes and against the middle






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






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






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






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






22. The change in a populations genetics






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






24. Direct competition for mates with the same sex






25. Cells that can turn into other cells






26. Differences in appearances between the sexes






27. 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






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






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






30. The idea that characteristics can enhance an organisms survival






31. Sometimes different species share common ancestors






32. Mate choice; one sex chooses their mate






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






34. Directional selection - Disruptive selection - Stabalizing






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






36. Change in alleles due to random chance






37. Sexual partners chosen based on some characteristics






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






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






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






41. First to publish mechanisms for evolution; Had 2 idea: Use and disuse - use it more gets bigger; less it disappears - Inheritance of acquired characteristics - pass on changes to offspring






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






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






44. Capable of asexual reproduction; most are not






45. 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






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






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






48. 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






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






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