nucleósidos
Nucleosides are organic molecules that serve as the building blocks of nucleic acids, DNA and RNA. Each nucleoside consists of two components: a nitrogenous base and a sugar molecule. The nitrogenous base is a heterocyclic aromatic compound that contains nitrogen. There are five main types of nitrogenous bases found in nucleosides: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). Adenine, guanine, and cytosine are found in both DNA and RNA, while thymine is specific to DNA, and uracil is specific to RNA.
The sugar molecule attached to the nitrogenous base is a pentose sugar, meaning it has five carbon
Nucleosides are crucial for cellular processes. They are not only precursors to DNA and RNA but also
