Nucleotide- Definition, Characteristics, Biosynthesis, Functions
Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are … Meer weergeven A nucleotide is composed of three distinctive chemical sub-units: a five-carbon sugar molecule, a nucleobase (the two of which together are called a nucleoside), and one phosphate group. With all … Meer weergeven Theories about the origin of life require knowledge of chemical pathways that permit formation of life’s key building blocks under plausible prebiotic conditions. The RNA world hypothesis holds that in the primordial soup there existed free … Meer weergeven Several nucleotide derivatives have been used as antivirals against hepatitis and HIV. Tenofovir disoproxil, Tenofovir alafenamide and Sofosbuvir are examples of NRTI used against hepatitis.
