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 ...

In DNA, 2-deoxy-D-ribose molecules link together through phosphate groups to form a sugar-phosphate backbone. This backbone provides the structural framework for DNA, holding the nitrogenous bases ...

The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...
