Biosynthesis of Nucleotides

Biosynthesis of nucleotides is the process by which cells produce the building blocks of DNA and RNA. It involves creating two main parts: a sugar (ribose or deoxyribose) and a nitrogenous base (like adenine or cytosine). The bases are formed through a series of chemical reactions starting from simpler molecules, adding nitrogen and other elements. These bases then attach to the sugar to form nucleotides, which are the units that store genetic information. This process is tightly regulated to ensure cells have the right amount of nucleotides for DNA and RNA synthesis, essential for growth and function.
