Which of the following characteristics of Figure 1 best shows that the fragment is RNA and not DNA? A
The 5' to 3' orientation of the nucleotide chain
B
The identity of each nitrogenous base
С
The charges on the phosphate groups
D
The type of bond linking the nucleotides together

I’m pretty sure it’s B

Explanation:

there is a uracil nitrogenous base in it and only rna has uracil whereas dna has thymine

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
