Which of the following is not a part of the nucleotide of DNA?

🔑Key Points:
Amino acids are not a part of the nucleotide structure of DNA.
The nucleotide is the building block of DNA and is composed of three parts: a nitrogenous base (adenine, guanine, cytosine, or thymine), a deoxyribose sugar, and a phosphate group.
The nitrogenous base and deoxyribose sugar make up the nucleoside, and the addition of a phosphate group forms the nucleotide.
Amino acids, on the other hand, are the building blocks of proteins, and are not directly involved in the structure of DNA. 

🔴Additional Information:
Nitrogenous base: Nitrogenous base is one of the three parts that make up a nucleotide, along with a deoxyribose sugar and a phosphate group. The nitrogenous bases in DNA are adenine, guanine, cytosine, and thymine. These bases pair up with each other in a specific way to form the rungs of the DNA ladder, which is the double helix structure of DNA.
Deoxyribose sugar: Deoxyribose sugar is another component of a nucleotide. It is a five-carbon sugar that makes up the backbone of DNA along with the phosphate group. The nitrogenous bases are attached to this sugar molecule, and it is the specific sequence of these bases that determines the genetic information encoded in DNA.
Phosphoric acid: Phosphoric acid, also known as a phosphate group, is the third component of a nucleotide. It is a molecule made up of phosphorus and oxygen atoms, and it gives DNA its negative charge. The phosphate groups form the backbone of the DNA strand along with the deoxyribose sugar.
