The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.
Nucleotides
alternating deoxyribose sugar molecules and phophate groups
DNA Molecules
DNA helicases are proteins, while DNA molecules are nucleotides.
Daughter moloqules are newer than DNA moloqules
two molecules are formed, each with the original "upright"
The two molecules that alternate to form the backbone of a DNA molecule are deoxyribose sugar and phosphate groups. These molecules form a repeating pattern along the length of the DNA strand, with the nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the deoxyribose sugar molecules.
Deoxyribose
The phosphate groups and deoxyribose molecules makes up the DNA ladder.
DNA molecules
The DNA molecule.
Deoxyribose sugars and phosphates make up the backbone of DNA.
Nucleotides are the molecules that make up the D.N.A.
Nucleotides

amino acids or polypeptides
Because they are splitting to make more dna
