Following the Chargaff's rule, if thymine is 28% in a double stranded DNA, then the percentage of guanine will be 22%.
Chargaff's rule was given by Erwin Chargaff. It states that since thymine forms bonds with adenine therefore in a double stranded molecule of DNA their numbers will be equal. The same case can be applied to the nucleotides guanine and cytosine.
DNA stands for Deoxyribonucleic Acid. It is a double stranded molecule which is helical in shape. It is the genetic material in majority of the living organisms. The constituents of DNA are deoxyribose sugar, phosphate group and the 4 nitrogenous bases, namely, adenine, guanine, cytosine and thymine.
