What is the composition of a DNA fragment?

DNA is formed by the union of many deoxyribonucleotides, it is composed of two long chains of polynucleotides, which are kept together due to the interactions of their nitrogenous bases.

Explanation:

DNA is the carrier of genetic information, it can therefore be said that genes are made up of DNA. Nucleotides are the monomeric units of DNA and RNA, also known as nucleic acids, which are responsible for storing and transmitting genetic information from one generation to another. The primary structure of DNA is the deoxyribonucleotide sequence of one of the strands. Genetic information is contained in the exact order of nucleotides
