adenine, uracil, cytosine, and guanine

Detailed explanation-1: -Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, the thymine is replaced by uracil (U). The chemical structures of A, G, C, T, and U are shown in (Fig.
Detailed explanation-2: -RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA. Like thymine, uracil can base-pair with adenine (Figure 2).
Detailed explanation-3: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers made up of long chains of nucleotides.
Detailed explanation-4: -Two nitrogen-containing bases (or nucleotides) that pair together to form the structure of DNA. The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
Detailed explanation-5: -Nitrogenous Bases in RNA RNA uses adenine, guanine, and cytosine, like DNA. However, in place of thymine, RNA uses uracil. Uracil pairs with adenine and guanine and cytosine pair together. Uracil and adenine form two hydrogen bonds, just like thymine and adenine do in DNA.
