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. Sexual partners chosen based on some characteristics






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






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






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






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






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






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






8. 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






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






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






11. 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






12. The idea that characteristics can enhance an organisms survival






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






14. Selects for the extremes and against the middle






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






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

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






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






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






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






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






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






23. Cells that can turn into other cells






24. Directional selection - Disruptive selection - Stabalizing






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






26. 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






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






28. A subset of a population colonizes a new area






29. Differences in appearances between the sexes






30. The organism with the most advantageous traits will survive






31. Mate choice; one sex chooses their mate






32. Capable of asexual reproduction; most are not






33. 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






34. One extreme is selected over the other






35. Sometimes different species share common ancestors






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






37. 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






38. Direct competition for mates with the same sex






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






40. A widely accepted idea with lots of evidence






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






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






43. The change in a populations genetics






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






45. Selects for the middle and against the extremes






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






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






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






49. 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






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