👉 In biology, a precursor is a molecule that serves as an initial step in the process of cell division. Precursors are essential for the growth and differentiation of cells into new tissues or organs. Examples of precursors include:
DNA (Deoxyribonucleic acid)
RNA (Ribonucleic Acid)
Protein
Carbohydrates
Precursors play a crucial role in regulating cell division, ensuring that cells divide evenly and efficiently over time.
