Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.). A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide.Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder.ther combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.). A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide.
DNA nucleotides consist of three parts: 1. A five-carbon sugar (hence a pentose) called deoxyribose. Deoxyribose, which has a hydrogen atom attached to its #2 carbon atom (d â¦ esignated 2') Deoxyribose-containing nucleotides, the deoxyribonucleotides, are the monomers of DNA. 2.n DNA the sugar present is deoxyribose, whereas ribose is present in RNA (the second fundamental difference). This sugar is bonded to a phosphate group, which is made up of four oxygen atoms that are bound to one phosphorous atom.
