Detailed explanation-1: -Both DNA and RNA consists of polymers of nucleotides. RNA is single stranded but DNA is double stranded. DNA polynucleotide contains thymine but RNA polynucleotide contains uracil.
Detailed explanation-2: -Uracil (/ˈjʊərəsɪl/) (symbol U or Ura) is one of the four nucleobases in the nucleic acid RNA. The others are adenine (A), cytosine (C), and guanine (G). In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine (T).
Detailed explanation-3: -The RNA molecule consists of a sequence of nucleotides, each containing a five-carbon sugar (ribose), a phosphate group, and a nitrogenous base. Uracil is one of four nitrogenous bases found in the RNA molecule: uracil and cytosine (derived from pyrimidine) and adenine and guanine (derived from purine).
