The genetic material for nearly all life on Earth. sequencingplugin-autotooltip__default plugin-autotooltip_bigSequencing: the procedure used to determine the sequence of a biological polymer such as DNA, RNA, or protein. Although there are indeed biochemical techniques that can be used to directly sequence RNA or protein, these methods are almost never used in modern molecular genetics research - instead, RNA technology invented in 1977 by Fredrick Sanger.
