👉 Nucleosynthesis is a process in which an element, usually carbon, combines with hydrogen and other elements to form new compounds. This process occurs through nuclear fusion reactions, where atoms combine into smaller nuclei called nucleons. The resulting compound is known as a nucleic acid or a nucleotide. Nucleosynthesis is a key event in the process of life, as it provides the building blocks for the majority of cell structures and organelles that make up living organisms.
