BIOMOLECULES AND ENZYMES

Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.

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: -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.
