Yes. the nucleotides are A, T, G, and C. A and T pair up and G and C pair up. For instance, if your known strand is AGTCAG then the second strand would have to be TCAGTC. Also, if there is a U in the strand, it takes the place of T. so the original strand would be AGTCAG and the unknown would have to be UCAGUC.
        
             
        
        
        
cellular respiration releases the greatest amount of energy or ATP.
Explanation:
In cellular respiration 38 ATPs in the process. 4 molecules of ATP are formed in glycolysis, 32 molecules in Oxidative phosphorylation. 
alcoholic fermentation: 2 ATP is formed
lactic acid cycle: 2 ATP is formed
photosynthesis: does not produce ATP instead ATP formed from the glucose formed is used in the process.
