Why It Matters: Modern Biology

Why describe and discuss techniques used in modern biology?

Over the decades, new techniques have been developed to study biology. Scientists recently mapped the complete human genome. New technologies were developed to help speed this process up. New techniques enable law enforcement to gather DNA evidence at crime scenes, which helps ensure they catch the right suspect. DNA based information can be applied to many such situations. Consider the following scenario.

On Memorial Day 1984, the remains of a soldier killed during the Vietnam War were laid to rest in the Tomb of the Unknown at Arlington National Cemetery. A decade later, however, questions began to arise about the identity of this unknown soldier.

Read on to learn how DNA can be used to solve these types of problems. Let’s put some biology to work for us!
