The composition, in mole‑fraction units, of one of the strands of a double helical dna molecule is [a] = 0.30 [a]=0.30 and [g] = 0.24 . [g]=0.24. this strand is the reference strand. what is the total [t] and [c] for the reference strand? [t] + [c] = [t]+[c]= what is the total [a] and [g] for the complementary strand? [a] + [g] = [a]+[g]= what is the total [t] for the complementary strand? [t] = [t]= what is the total [c] for the complementary strand? [c] = [c]=
