If you're referring to Stem Cell Research, Scientists can use that DNA to grow an organ that you might need to be replaced with a much lower risk of having the body reject it than if you took it from another person.

Scientist would want to extract DNA from plant cells in order to analysis the gene sequences that are coded in the DNA. By looking at the gene sequences they can determine what proteins the DNA codes for and see if they can alter the codons for those proteins to create a protein needed for another purpose. They could also use the understanding of what proteins the plant creates to see if it is possible to synthesize something with the plant, i.e. bio-pharmaceuticals synthesizing vaccines in tobacco plants

The most important aspect of colored photography was the cure for the Polio virus. In order for scientists to distinguish the difference between cells in a sample, they needed to use high resolution photographs. When the photos were taken, all the cells appeared in black & white, so scientists could not distinguish between the gamma cells and the beta cells. Gama cells are dark red in color and beta cells are dark blue. When the first color camera was used to document these microscopic cells, Dr. Francis Wellington was able to extract the gamma cells to use in creation of the vaccine.
