Osmosis video - Nucleotide metabolism

Nucleotide metabolism refers to the metabolic processes that involve the synthesis and breakdown of nucleotides. A nucleotide is a building block of DNA or RNA. Each nucleotide consists of a nitrogenous base, a sugar, and a phosphate group. Nitrogenous bases are divided into purines, which are adenine and guanine; and pyrimidines, which include cytosine, thymine, and uracil. The sequence of nitrogenous bases in DNA and RNA determines the identity of the genetic information found in living organisms.
