16.1 Cloning of a Gene
| | |
- Using recombinant DNA technology, bacteria and viruses can be genetically engineered to clone a gene.
- A genomic library contains bacteria or viruses that carry fragments of the DNA of a particular organism.
- The polymerase chain reaction (PCR) makes multiple copies of DNA segments. Analysis of the DNA usually follows.
| - What two enzymes are required to inject foreign DNA into a cell and what do they do?
Answer - What does PCR stand for and what is it used for?
Answer - What is DNA fingerprinting?
