Science / Genetics / DNA Sequencing: Plus and minus or 'primed synthesis' method, developed by sanger, dna is synthesized in vitro in such a way that it is radioactively labeled and the reaction terminates specifically at the position corresponding to a given base: the 'chemical' method, ssdna is subjected to several chemical cleavage protocols that selectively make breaks on one side of a particular base.

Science / Genetics / Junk DNA: Stretches of dna that do not code for genes: most of the genome consists of so-called junk dna which may have regulatory and other functions. Also called non-coding dna. MORE
