Cytosine is considered a polar molecule due to the presence of its amine (-NH2) and carbonyl (=O) functional groups, which can form hydrogen bonds and interact with water. The electronegativity differences between the atoms in its structure contribute to its polarity. Consequently, cytosine is soluble in polar solvents like water.

Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.

I can't see how.Note that the opposite is a different story: it is possible for a molecule to be nonpolar despite having no bonds that are not polar. For example, consider CCl4, which is nonpolar due to its geometry despite the individual C-Cl bonds each having a substantial polarity.
The shape is trigonal bipyramidal and all the atoms on the outside are the same so the charges cancel eachother. Nonpolar
