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 ...
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 left-handed Z-DNA double helix is held together by traditional Watson-Crick base pairs, but unlike righthanded B-DNA, which has major and minor grooves between the twists of its sugar-phosphate ...
DNA and RNA strands vary in length from less than ... In this analogy nucleotides are the teeth of the zipper; the ...
