Gene research. Researcher cutting pieces of deoxyribonucleic acid (DNA) from an agar sheets. The researcher is wearing protective clothing and a visor to prevent contamination of the sample. The DNA has been split up and its components separated by a process known as electrophoresis. Similar DNA fragments occupy certain areas of the agar because different fragments have a distinctive mobilities through the agar when an electric current is applied. By selecting these areas of the agar, the desired DNA fragments can be isolated and studied. DNA contains an organism's hereditary information.
