Q.1
Which best describes stem cells?
  • stem cells can only come from embryos
  • stem cells can only come from adult bone marrow
  • stem cells do not ever change
  • stem cells can develop into different specialized cells
Q.2
What is the primary purpose of using restriction enzymes in gel electrophoresis?
  • It restricts the number of base pairs that can be tested in a sample.
  • It makes the testing simpler by moving the strands into the gel faster.
  • It allows the DNA strands to be charged so the electrical current can send the strands into the gel.
  • It allows the strands of DNA to be cut into various lengths for testing.

Q.7
Which is a transgenic organism?
  • a mutation in an animal cell
  • an animal cell with no mutation
  • bacteria with antibiotic resistance
  • a plant with bacterial DNA
Q.8
Which best describes recombinant DNA?
  • DNA that has been deactivated by enzymes
  • DNA found in organelles other than the nucleus
  • inserted genes from one organism into another to direct it to produce a protein
  • genes developed when an egg nucleus and a sperm nucleus fuse to form a zygote
Q.9
Which would be the benefit of a transgenic crop?
  • decreased drought tolerance

  • An organism that has had another species' DNA put in it
  • A bacteria that reproduces asexually
Q.13
Which is a concern of scientists when genetically modifying plants?
  • Plants will pass on diseases to animals.
  • There will be a decrease in biodiversity.
  • Plants will have a longer growing season.
  • There will be a decrease in revenue for pesticide manufacturers.
Q.14
Which best describes a controversial issue associated with the use of genetically modified crops?
  • the use of genetically modified crops to increase potential yield
  • the short term use of genetically modified crops in famine stricken countries
