WebNucleic acids. There are two types of nucleic acids in biology: DNA and RNA. DNA carries the heritable genetic information of the cell and is composed of two antiparallel strands of nucleotides arranged in a helical structure. Each nucleotide subunit is composed of a pentose sugar (deoxyribose), a nitrogenous base, and a phosphate group.The two strands … WebJul 20, 2024 · The four oxygen substituents in phosphate groups are arranged about the central phosphorus atom with tetrahedral geometry, however there are a total of five bonds to phosphorus - four s bonds and one delocalized π bond.

WebJul 14, 2008 · Ru5P is then isomerized to ribose-5-phosphate (R5P) by ribose-5-phosphate isomerase. Alternatively, ribokinase can directly phosphorylate the C1 position of ribose to generate R5P [ 76 ]. R5P, from either glucose or ribose, is then converted to PRPP by the phosphorylation of R5P'sC1 position by PRPP synthetase.
