In the photosynthesis the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and the outer part is called thylakoid membrane is the stroma, where the light-independent reactions take place.
        
             
        
        
        
Answer: DNA bases are A,T,C,G and here we have U which is not a DNA base therefore being an RNA strand. RNA bases are A,C,U,G.

Answer:
DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.
Explanation:
Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.  
Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.
