The base content of a sample of nucleic acid is as follows: A = 31%,G = 31%,T = 19%,C = 19%.What conclusion should be drawn from this information?
A)This nucleic acid is double- stranded DNA.
B)This nucleic acid is made of RNA.
C)The purine/pyrimidine ratio in this molecule fits Chargaff's data.
D)The strands in this molecule are parallel rather than antiparallel.
E)This nucleic acid is single- stranded DNA.
