Question
1. For the formation of a strand of RNA from individual nucleotides, one would expect the entropy change in the reaction to be _________
- negative
- positive
- zero
1b. This entropy change is expected because _________
- one RNA strand can be randomized in more ways than several individual nucleotides
- formation of a strand of RNA from individual nucleotides requires energy
- formation of a strand of RNA from individual nucleotides releases energy
- one RNA strand can be randomized in fewer ways than several individual nucleotides
2. For the breaking down of a strand of DNA into individual nucleotides, one would expect the entropy change in the reaction to be _________
- negative
- positive
- zero
2b. This entropy change is expected because _________
- breaking down of a strand of DNA into individual nucleotides requires energy
- one DNA strand can be randomized in fewer ways than several individual nucleotides
- one DNA strand can be randomized in more ways than several individual nucleotides
- breaking down of a strand of DNA into individual nucleotides releases energy.
Explanation / Answer
1. The answer is negative. It is because, several nucleotides comine to form a single RNA and as a result, the degree of freedom of individual nucleotide is lost.
1b. The entropy change is expected because, one RNA strand can be randomized in fewer ways than several nucleotides.
2. The answer is positive. It is because breaking of DNA will result in formation of several nucleotides and each molecule will have their their degrees of freedom, and entropy will increase.
2b.The entropy change is expected because one DNA strand can be randomized in fewer ways than several individual nucleotides.
