Quote:Is it possible that alien life uses DNA with the same bases as ours but a different coding scheme?In the Terragen Sphere there are several worlds with biospheres that use DNA (including Seattle, a world described recently by Cray). However it is inevitable that such worlds use a different DNA coding system to Earth, since the chance against the same code occurring on two planets in the Visible Universe is very low indeed.
