Explain how does cell structure relates to cell function?

Cell function depends on cell structure because different cell types have different structures, as well as functions. Prokaryotic cells have no nucleus, and they are unicellular. Eukaryotic cells have a nucleus and are multi-cellular. Both have organelles. Hope this helped :)

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
