Dna and rna share a number of similarities but they also differ in certain aspects of their structure which nitrogenous base is found in dna but is not found in dna

Uracil

Uracil is the nitrogenous base that is found in RNA but not present in DNA.

Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).
