A life-form from another universe is found to have nucleic acid which includes six different bases - R,S,T,X,Y and Z. The percen
nalin [4]

R, S, and T always have the same percentage composition, while X, Y, and Z always have the same percentage composition. Chargaff's rule is then a viable theory that can be used in this situation.

  • The DNA of any species of any organism must have a 1:1 stoichiometric ratio of the purine and pyrimidine nucleotides, according to Chargaff's principles.
  • More specifically, the ratio of guanine and adenine to cytosine and thymine must be the same. This pattern is present in both the strands of the DNA.
  • The formula comes as A + G = T + C = 1
  • In this universe there are six base pairs R,S,T,X,Y and Z. composition of R,S and T is always same thus these can be considered the purines.
  • The percentage composition of X,Y and Z is always the same thus these can be considered the pyrimidines.
  • applying Chargaff's rule to these bases:

R + S + T = X + Y + Z

= 1:1

Thus, the nucleic acid will contain six base pairs where bonds are formed between RX, SY and TZ.
