    36 thymine

    Explanation:

    DNA is a polynucleotide having double helical structure. The Each helix of DNA is made of nucleotides. Each nucleotide has a pentose sugar, phosphate and a nitrogenous base. Both the helices are joined by corresponding bases through hydrogen bond. The base pairing in the DNA double helix is specific. The purine adenine (A) always pairs with the pyrimidine thymine (T) the purine guanine (G) always pairs with the pyrimidine cytosine (C). Therefore, the number of adenine is 36 then the number of thymine will be 36. Similarly if the number of cytosine is given 24, then the number of guanine will be required 24 not 36.
