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. Differences in appearances between the sexes






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






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






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






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






8. A subset of a population colonizes a new area






9. Selects for the extremes and against the middle






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






11. 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






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






13. 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






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






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






16. Humans selecting certain traits in domestic organisms






17. Results in a genetically identical inidvidual






18. 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






19. Form of reproduction more used because it creates Variation






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






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






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

23. Mate choice; one sex chooses their mate






24. Selects for the middle and against the extremes






25. The organism with the most advantageous traits will survive






26. 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






27. Cells that can turn into other cells






28. 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






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






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






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






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






33. The change in a populations genetics






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






35. Way more offspring are produced than by sexual reproduction






36. A widely accepted idea with lots of evidence






37. 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






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






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






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






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






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






43. The idea that characteristics can enhance an organisms survival






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






45. Change in alleles due to random chance






46. Related organisms have similar development plans






47. Sometimes different species share common ancestors






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






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






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