Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA.
Do you mean "nucleotide"? Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA.
Somewhat the difference between a brick and a brick wall. Chromosomes are made up of DNA molecules collected in units called genes ( leaving all else aside ) with attendant proteins, such as the histone proteins DNA wraps around.
Nucleotides are the monomer units that make up a DNA molecule. DNA nucleotides are composed of a deoxyribose sugar, a nitrogenous base, and a phosphate group.
DNA Molecules
DNA helicases are proteins, while DNA molecules are nucleotides.
