Researchers were investigating the wound-healing properties of deoxyribose, a sugar critical in the structure of DNA. While applying the sugar to skin injuries on laboratory mice, scientists ...

Each nucleoside triphosphate is made up of three phosphates (represented here by yellow spheres), a deoxyribose sugar (beige rectangle) and one of four bases (differently colored cylinders).

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
