Ascientist isolates a number of non photosynthetic prokaryotes which structure would be found in theses cells

As these cells are non-photosynthetic, all other organelles would be found in these cells except for chloroplasts which contain photosynthetic pigments used for photosynthesis. A few examples of structures found within these cells would be cell wall, cell membrane, cytoplasm, ribosomes, nucleoloid and many others. Do note that prokaryotic cells do not have organelles with membranes hence they do not have mitochondria or lysosomes or endoplasmic reticulum etc.

Explanation:

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.
