If a DNA chain is 26 guanine what percentage of it is thymine?

In a DNA molecule, guanine (G) pairs with cytosine (C), while adenine (A) pairs with thymine (T). Therefore, the amount of thymine in the DNA cannot be directly determined from the amount of guanine alone. However, if we assume this DNA molecule is double-stranded and follows Chargaff's rules, and if there are no other bases present, the percentage of thymine would depend on the total number of nucleotides. To calculate the percentage of thymine, we would need additional information about the total number of bases in the DNA chain.
