If double stranded DNA has 14% (guanine), what percent A (adenine), T (thymine) and C (cytosine) would you expect?

If in a double stranded DNA the percentage of guanine is 14%, the percentage of the other bases of the molecule will be 14% for cytosine, 36% for adenine and 36% for thymine.

Explanation:

In the DNA molecule resides all the information of the genome of a living being, according to a specific sequence of nitrogenous bases adenine, guanine, cytosine and thymine. These bases are complemented -purine with pyrimidine- following the rule of base complementarity between one chain and another.

Knowing the percentage that exists of a base, the percentage or proportion of the other nitrogenous bases in a DNA molecule can be determined, approximately, following the rule of Chargaff's base pair.

     Chargaff established in his observations that the DNA of a cell has a purine:pyrimidine ratio of 1:1, so there should be an equivalent amount of guanine for cytosin and a similar amount of thymine for adenine, since they are complementary bases.

According to the law of the base pair, if there is 14% in a DNA strand, there will be a 14% in the molecule:

This rule applies to both chains, since the percentage of bases in a single chain will depend on the specific sequence of bases it has.
