Betel is a developing a model of the process of photosynthesis. one of her goals is to identify the products of photosynthesis that will later be used to assemble sugars, lipids, amino acids, and other essential compounds for the organisms. in which part of the model should the products be identified?

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

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.
