  1. 2. Not only has this enormous amount of data required careful storage, organization, and indexing of sequence information, but it also has created a new field of study.
  2. 4. involves separating these DNA fragments using gel electrophoresis in order to obseve the distainct banding patterns that are unique to every indicidual.
  3. 5. This process, in which two closely related organisms are bred to have the desired traits and to eliminate the undesired ones in future generations, is called
  4. 10. is the totalt DNA present in the nucleous of each cell
  5. 12. The process by which desired traits of certain plants and animals are selected and passed on to their future generations is called
  6. 14. Once the sequence of a DNA fragment is know, a technique called the_____ can be used to make millions of copies of a specific region of a DNA fragment.
  7. 15. Some of the bacterial cells take up the recomniant plasmid DNA through a process called
  8. 17. small, circular, double stranded DNA molecules that occur naturally in bacteria and yeast cells
  9. 18. These variations in the DNA sequence that occur when a single nucleotide in the genome is altered are called
  10. 20. involves breedin an organism that has the unknown genotype with one that is homozygous recessive for the disired trait.

  1. 1. Such organisms, genetically engineered by inserting a gene from another organism are called
  2. 3. technology that involves manipulating the DNA
  3. 6. AN enzyme normally used by cells in DNA repair and replication called
  4. 7. An electric current is used to separat DNA fragments according to the size of the fragments in a process called
  5. 8. Therefore, regions of linked variations in the human genome, known as
  6. 9. When DNA fragments have been separated by gel electrophoresis, gragments of a specifice size can be removed from the gel and combined with DNA fragments from another source.
  7. 11. Large numbers of identical bacteria, each containing the inserted DNA molecules, can be produced through this process called
  8. 13. some types of bacteria contain powerful defenses against viruses.
  9. 16. Are tiny miscroscope slides or silicon chips that are spotted with DNA fragments.
  10. 19. The study of how genetic inheritance affects the body's response to drugs is called
