apply chargaffs decide how many guanine bases and length of DNA will have if it has 26 cytosine bases. explain.

According to Chargaff's rule, if a DNA molecule has 26 cytosine base molecules it will also have 26 guanine molecules.

Explanation:

DNA is formed by the bases adenine guanine, thymine and cytosine, distributed in its two strands whose proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.

Chargaff found that in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there should be the same amount of thymine as adenine and a similar amount of guanine for cytosine, according to the complementarity of the bases.

According to Chargaff, if a DNA molecule contains 26 cytosine bases —one pyrimidine— then it also contains 26 guanine molecules, one purine.

In the case that the molecule has a total of 100 nitrogenous bases, the amount of the other bases can also be known:
