D. Uracil

Answer :

DNA and RNA contain four bases each. The nitrogenous bases in RNA are Adenine (A), Guanine (G), Cytosine (C) and Uracil (U).

DNA contains four nitrogenous bases, namely Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). Uracil is not present in DNA. Thus, option (iv) is correct.


Options(i), (ii) and (iii) are incorrect because these nitrogenous bases are there in DNA.
