Detailed explanation-1: -Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals.
Detailed explanation-2: -Nucleic Acids: DNA and RNA 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-3: -DNA is known as the deoxyribonucleic acid. It is comprised of nitrogenous bases, deoxyribose sugar, and phosphate backbone. Every DNA is unique to each person although the DNA is composed of the same nitrogen-based molecules. This is because the sequence of nitrogen bases is different in every person.
