Ernie Reed BIO-013/ Stem Cell Research Sullivan 11.10.2010 STEM CELL RESEARCH What is a stem cell? One can define a stem cell as a cell type that is found in many tissues. This particular cell is unique in the fact that it can divide itself over and over virtually to an infinite number. This process of reproduction ensures that the cells can restore other cells that may have gotten damaged; this process may only occur if the person is still living. The same goes for animals. As the stem cell

Calvin Williams Chapter 20 1. Advances in recombinant DNA technology allow scientists to work with smaller fragments of DNA‚ give them more tools to dissect and analyze DNA‚ and also allow for them to make many copies of a strand of DNA. 2. Restriction enzymes are made by bacteria to cut up invading DNA. They target specific base sequences in the DNA and then work to cut out those sequences from the DNA. 3. When a restriction enzyme cuts out a portion of DNA‚ it will sometimes leave a sticky
