Question
Imagine two DNA duplexes X and Y. According to calculations using the nearest neighbor method the two duplexes have the same standard enthalpy of helix formation, but the formation of duplex X results in a greater standard entropy loss than does the formation of duplex Y Which of the following are likely to be correct: Select one: a. Duplex X will have a higher melting temperature than duplex Y b. Duplex X will have the same melting temperature as duplex Y c. Graphs of 1/Tm versus In(CT) for the two duplexes will be parallel. d. Graphs of 1/Tm versus In(CT) for the two duplexes will converge at low CT e. Graphs of 1/Tm versus In(CT) for the two duplexes will be superimposable. f. None of the above.Explanation / Answer
The correct option is option (a) only where the duplex DNA X was having a higher melting point than Y because of that when there is a formation of the duplex in results in the standard entropy increase...
