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. A subset of a population colonizes a new area






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






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






4. The change in a populations genetics






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






6. 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






7. Selects for the extremes and against the middle






8. Direct competition for mates with the same sex






9. Cells that can turn into other cells






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






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






12. The idea that characteristics can enhance an organisms survival






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

14. The organism with the most advantageous traits will survive






15. 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






16. 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






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






18. Results in a genetically identical inidvidual






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






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






21. Humans selecting certain traits in domestic organisms






22. 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






23. Way more offspring are produced than by sexual reproduction






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






25. Related organisms have similar development plans






26. Selects for the middle and against the extremes






27. A widely accepted idea with lots of evidence






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






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






30. Sometimes different species share common ancestors






31. Differences in appearances between the sexes






32. Sexual partners chosen based on some characteristics






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






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






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






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






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






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






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






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






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






42. 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






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






44. 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






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






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






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






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






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






50. Mate choice; one sex chooses their mate
