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. Direct competition for mates with the same sex






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






6. Sexual partners chosen based on some characteristics






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






8. Selects for the extremes and against the middle






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






10. 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






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






12. 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






13. Differences in appearances between the sexes






14. A widely accepted idea with lots of evidence






15. Results in a genetically identical inidvidual






16. Capable of asexual reproduction; most are not






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






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






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






20. Humans selecting certain traits in domestic organisms






21. Way more offspring are produced than by sexual reproduction






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






23. The idea that characteristics can enhance an organisms survival






24. 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






25. 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






26. Change in alleles due to random chance






27. 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






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






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






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






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






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






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






34. Sometimes different species share common ancestors






35. The organism with the most advantageous traits will survive






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






37. The change in a populations genetics






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






39. 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






40. Related organisms have similar development plans






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






42. 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






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

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






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






46. Mate choice; one sex chooses their mate






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






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






49. A subset of a population colonizes a new area






50. Selects for the middle and against the extremes
