The structure of DNA is called a "double helix" which is simply a twisted ladder. Or, twisted staircase.
- DNA is made up of a double helix. To put it another way, it is a spiral-shaped, double-stranded molecule. Deoxyribose sugars alternate with phosphates to create the molecule's exterior, or the rails of the stairway. The "backbone" of the molecule is another name for this area.
- The double helix, which resembles a twisted ladder, is the shape of DNA. Sugar and phosphate molecules alternately make up the sides of the ladder. It is deoxyribose, the sugar. The ladder's rungs are made up of pairings of the four different nitrogen bases.
- A lengthy polymer is created when the phosphates and sugars of nearby nucleotides connect. They demonstrated how the twisted uprights of the DNA ladder are made up of alternating deoxyribose and phosphate molecules. The complementary pairings of nitrogen bases that make up the ladder's rungs are A always paired with T and G always paired with C.
- DNA Replication Deoxyribonucleic acid, also known as DNA, resembles a long, spiralling ladder. It only has carbon, hydrogen, oxygen, nitrogen, and phosphorus as its main atom types. The sides of the DNA ladder, or the sugar-phosphate backbone, are made up of combinations of these atoms.
