What are the similarities between ribonucleotide and deoxyribonucleotide?

Both are nucleotides, serving as the monomers of RNA and DNA, respectively. Another similarity is that both form phosphodiester bonds through the 5’-3’ direction, connecting with another nucleotide to build the polynucleotide chain. They also both consist of three essential components: a nitrogenous base (Adenine, Guanine, or Cytosine), a pentose sugar (ribose or deoxyribose), and a phosphate group.
