genes. Each nucleotide has a ribose sugar attached to the carbon, a base that
is composed of purines and pyrimidines, a negatively charge phosphate groups
and a hydroxyl group which causes helix to mostly adopt the A-form geometry.</span>
The absolute magnitude is the magnitude the stars would have if viewed from a distance of 10 parsecs or some 32.6 light years. Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same absolute magnitude, but closer, stands even higher in the list.
