In DNA, 2-deoxy-D-ribose molecules link together through phosphate groups to form a sugar-phosphate backbone. This backbone ...

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 ...

The structure of DNA can also be described as a ladder. The chemical backbones of the ladder are made up of sugar and phosphate molecules that are connected by chemical bonds. The rungs of the ...

The famous DNA double helix is considered right-handed, meaning its spiral strands — a sugar-phosphate backbone — twist to the right. (To picture this, make a thumbs-up with your right hand ...

Meiotic recombination involves formation and repair of double-strand breaks generated by the Spo11 protein through a topoisomerase-like reaction in which a tyrosine severs the DNA backbone and ...
