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. 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






2. Way more offspring are produced than by sexual reproduction






3. 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






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






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






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






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






8. Selects for the middle and against the extremes






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






10. Humans selecting certain traits in domestic organisms






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






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

13. One extreme is selected over the other






14. Results in a genetically identical inidvidual






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






16. Sometimes different species share common ancestors






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






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






19. 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






20. A subset of a population colonizes a new area






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






22. Selects for the extremes and against the middle






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






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






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






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






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






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






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






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






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






32. 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






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






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






35. Form of reproduction more used because it creates Variation






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






37. 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






38. Direct competition for mates with the same sex






39. 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






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






41. The organism with the most advantageous traits will survive






42. Related organisms have similar development plans






43. The idea that characteristics can enhance an organisms survival






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






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






46. Mate choice; one sex chooses their mate






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






48. Differences in appearances between the sexes






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






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