One of the most recent and exciting areas in biology focuses on defining the complete genetic sequence, or the genome, of organisms populating this planet. These genetic sequences are the blueprints for proteins, the molecules that make the physical and chemical processes of life happen. When the genomes of different organisms are compared, we can frequently pinpoint the genes responsible for congenital conditions or susceptibility to disease. This information will have an impact on all the disciplines in the life sciences well into the next century as researchers study the function, structure, and evolutionary history of all biological systems. Using the information carried in our chromosomes and understanding how these chemicals translate code into action has given rise to dynamic collaborations among all biologists who seek to unravel the mysteries of life.
