Something that is positioned or oriented in the opposite direction or manner to something else.
From anti- (opposite) + -trope (from Greek tropos, a turn or direction). This is a technical term that emerged in biology and botany to name structures that oppose each other directionally.
Antitropes demonstrate a fundamental principle of nature: opposites and mirror images appear everywhere, from DNA's double helix to the way your left and right hands mirror each other perfectly.
