WebJan 19, 2024 · DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. WebPhosphate group. DNA (and RNA) are polymers made up of five-carbon sugars, organic nitrogen-containing bases, and phosphate groups. Examine the view of DNA labeled …

WebMar 27, 2024 · The phosphate group connects successive sugar residues by bridging the 5′-hydroxyl group on one sugar to the 3′-hydroxyl group of the next sugar in the chain. These nucleoside linkages are called phosphodiester bonds and are the same in RNA and DNA. Biosynthesis and degradation WebThe four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T … WebThe phosphate groups present in the nucleotides are derived from phosphoric acid. It has a general formula of (PO 4) 3- and it is found in the nucleotides as mono, di or tri-phosphates. The nucleotide containing one, two, and three phosphates is monophosphate, diphosphate, and triphosphate. implausible significado wikipedia
