The Base Pairs
The outside of the DNA ladder is made up of a sugar-phosphate backbone. The sugar in DNA is deoxyribose, which alternates with phosphate groups to form the backbone. The nitrogenous bases are attached to this sugar-phosphate backbone on the inside of the ladder.
Phosphate and sugar make up the sides of a DNA ladder.
The phosphate groups and deoxyribose molecules makes up the DNA ladder.
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.
Heck No!
Sugar used in the DNA ladder is a five carbon sugar known as deoxyribose.
Nucleotides are found along the sugar-phosphate backbone of DNA, which forms the "twisted ladder" structure of the double helix. They are the building blocks of DNA and consist of a sugar, a phosphate group, and a nitrogenous base.
on the outside of the DNA strand is the phosphate and sugar, only the sugar are connected across to the other half with the A&T and C&G
