Differential Display: A Technical Overview

Since the completion of the human genome-sequencing project, scientists are now able to read the code of all human genes stored on the 46 chromosomes of the human genetic library. However, we are far from reaching an understanding of the functional relationships existing between more than a tiny fraction of these genes. The value of the human genome-sequencing project, beyond the simple collation of data, has been to teach us that it is possible to take a highly intensive analytical approach to the study of human systems in health and disease (1 –4 ).
