Which of the following monomers would be used to make the double helix of a DNA molecule?

A monomer made up of a nitrogenous base, a five-carbon sugar, and a phosphate group bonded together.

A monomer with an amino group, carboxylic acid, hydrogen atom, and R group bonded to a central carbon atom.

A monomer with the formula C6H12O6. Five carbon atoms and one oxygen atom form a hexagonal ring, with the other atoms bonded to that ring.

A molecule made up of four carbon rings with other atoms bonded to those rings.

A monomer made up of a nitrogenous base, a five-carbon sugar, and a phosphate group bonded together.

The smallest units of DNA are called nucleotides. These are organic molecules that serve as building blocks of DNA and RNA. They are monomers or subunits of nucleic acids like RNA and DNA. It is made up of a nitrogenous base, deoxyribose (five-carbon sugar), and at least one phosphate group. They serve an important role in the metabolism of cells because they carry packets of energy in the form of nucleoside triphosphates (e. g. ATP, GTP, CTP, and UTP). They also play an important factor in cell signaling through enzymatic reactions and productions.
