Rock exposed at the Earth's surface in the form of a more or less horizontal surface, usually with crevices or joints.
Industry:Natural environment
The conversion of denatured protein or DNA to its native configuration. This is rare for proteins. However, if DNA is denatured by heating, the two strands separate. If the heat-denatured DNA is then cooled slowly, the double stranded helix reforms .
