DNA sequences can act as "tape measures of evolution". Scientists analyzing the human genome sequence were surprised to find that some regions of the human genome that are most highly conserved (similar to comparable regions in other species) don't code for proteins at all. Given what you've learned about "genes" speculate on reasons why this might be so.

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
