a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA ...
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality ...

Located In Canada, Last Chance Lake May Mimic The Ideal Conditions For Life To Emerge On Earth Approximately Four Billion Years AgoPhosphate is essential for making various life-forming compounds, such as nucleotides, which are the building blocks of DNA and RNA. Phosphate is found in every living being, but it is extremely ...
RNA is formed by linking molecules of ribose (a monosaccharide) with phosphate groups that bind to four types of nitrogenous ...
In order for these RNA ligases to repair breaks formed by transesterification, the 2’,3’-cyclic-PO 4 and 5’-OH ends must first be “healed”. End-healing entails hydrolysis of the 2’,3’-cyclic phosphate ...
