Detailed explanation-1: -The five-carbon sugar ring and the content of the nitrogenous base between DNA and RNA are slightly different from each other. 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).

Detailed explanation-2: -The adenosine phosphate nucleotides have ribose as the five carbon sugar and adenine as the nitrogenous base. These nucleotides differ in the number of inorganic phosphate groups phosphorylated to the ribose, which can vary from one to three.

Detailed explanation-3: -In RNA strands, thymine is replaced by uracil. Also, the sugar part of the nucleotides in RNA is different than the one in DNA, having one extra oxygen.

Detailed explanation-4: -The five bases that are found in nucleotides are often represented by their initial letter: adenine, A; guanine, G; cytosine, C; thymine, T; and uracil, U. Note that A, G, C and T occur in DNA; A, G, C and U occur in RNA.

Detailed explanation-5: -Explanation: Nitrogenous bases are split into two different types: the purines (adenine and guanine) and the pyrimidines (thymine, cytosine, and uracil). A purine will hydrogen-bond to a pyrimidine. Adenine always bonds with thymine (in DNA ) or with uracil (in RNA ) with two hydrogen bonds.
