A nucleotide, which is comprised of a nitrogenous base, a pentose sugar, and a phosphate group, is the monomer of DNA that forms the building blocks of its structure
The monomer of DNA is known as a nucleotide. A nucleotide is composed of three components: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group. Nucleotides are the basic building blocks of DNA, which join together to form long chains, or polynucleotides, that make up the DNA double helix. Each nitrogenous base in a nucleotide is linked to a sugar molecule, which is then attached to one or more phosphate groups, creating the backbone of the DNA structure.
So, nucleotides are the essential monomers that combine to create the complex structure of DNA, allowing it to carry genetic information.
