Detailed explanation-1: -DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
Detailed explanation-2: -DNA, which stands for deoxyribonucleic acid, resembles a long, spiraling ladder. It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. Combinations of these atoms form the sugar-phosphate backbone of the DNA–the sides of the ladder, in other words.
Detailed explanation-3: -The two sides of the DNA ladder are held together loosely by hydrogen bonds.
Detailed explanation-4: -The chemical backbones of the double helix are made up of sugar and phosphate molecules that are connected by chemical bonds, known as sugar-phosphate backbones. The two helical strands are connected through interactions between pairs of nucleotides, also called base pairs.
Detailed explanation-5: -The DNA is made up of sugar and a phosphate backbone.
