The last few years have seen an inundation of information about the identification of genetic information and its manipulation. There are articles in the newspaper several times a week about this technology. Today we are going to take a quick glimpse at how some of this works. Two Facets There are generally two things that people are interested in doing with genetic material.
Some people compare the DNA from two or more sources.
Sometimes it is simply to identify a person or organism. Other times it is to see how closely individuals are related. The other thing that people are trying to do is to manipulate the DNA information. They want to change it. That will, of course, result in an organism that has the potential to produce different proteins.
