DNA Sense
Molecular biologists call a single strand of DNA sense (or positive (+) ) if an RNA version of the same sequence is translated or translatable into protein. Its complementary strand is called antisense (or negative (-) sense). Sometimes the phrase coding strand is encountered; however, protein coding and non-coding RNA's can be transcribed similarly from both strands, in some cases being transcribed in both directions from a common promoter region, or being transcribed from within introns, on both strands (see "ambisense" below).

Famous quotes containing the words dna and/or sense:
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
“There is the guilt all soldiers feel for having broken the taboo against killing, a guilt as old as war itself. Add to this the soldier’s sense of shame for having fought in actions that resulted, indirectly or directly, in the deaths of civilians. Then pile on top of that an attitude of social opprobrium, an attitude that made the fighting man feel personally morally responsible for the war, and you get your proverbial walking time bomb.”
—Philip Caputo (b. 1941)
