Reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species. The number of molecules in one mole is the same for all substances; this number is known as Avogadro’s number (6.022140857 × 10 23). This session will explain how DNA is replicated prior to cell division. Polar molecules also form when the spatial arrangement of chemical bonds leads to a more positive charge on one side of the molecule than the other.
