  1. 3. us a technique that allows biologist to make copies if genes
  2. 4. Is the continued breeding of individuals with similar characteristic
  3. 7. In gel electrophoresis, DNA fragments are placed at one end of a porous gel, and an electric voltage is applied to the gel
  4. 8. making a exact copy of something
  5. 9. DNA can be extracted from most cells by a simple chemical procedure the cells are opened and the DNA is separated from the other cell parts
  6. 10. the individuals produced by such crosses are often hardier than either parents
Down
  1. 1. is the crossing of dissimilar individuals to bring together the best of both organisms
  2. 2. Allows only those organism with dissimilar characteristics to produce the next generation
  3. 5. Most DNA molecules are too large to be analyzed, so biologist cut them into smaller fragments using restriction enzymes
  4. 6. a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge
