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 ...

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 ...

In the case of DNA and RNA, these monomers are nucleotides. Nucleotides themselves are composed of three distinct parts: sugar, phosphate, and a nitrogenous base. Here's what each of those really ...

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 ...

RNA, or ribonucleic acid, is a essential biological molecule that plays a crucial role in various cellular processes. It is a polymeric molecule composed of nucleotides, each containing a ribose sugar ...

They are the building blocks of DNA and RNA, which store and transmit genetic information. Nucleotides also play crucial roles in various cellular processes, including energy transfer and enzymatic ...
