Narrator: This is Science Today. Our chromosomes are made up of DNA and within that DNA are genes that encode the proteins that become the working parts of the cell. Matthew Coleman, a senior scientist at the Lawrence Livermore National Laboratory, says trying to find all the genes out there has been a very difficult task.
Coleman: Even though you hear about we've completed the human genome, if we considered the human genome to be a book, we've kind of found all the words in the book but we don't exactly understand the chapters and the paragraphs and the sentences that link it all together that help us to understand and to read the book.
Narrator: So Coleman and other scientists within the Lab's Biotechnology Research Program, have developed a sophisticated process that identifies all the genes that belong to a specific part of each chromosome.
Coleman: It's definitely a very nice technology because it overcomes some of the slowness that was in some of the more traditional approaches that are used.
