It differs from DNA chemically in two respects: (1) the nucleotides in RNAare ribonucleotides—that is, they contain the sugar ribose (hence the name ribonucleic acid) rather than deoxyribose; (2) although, like DNA,RNA contains the bases adenine (A), guanine (G), and cytosine (C), it contains the base uracil (U) .
B. Only the “Analysis” section includes specific data comparisons, and only the “Conclusion” section suggests further research.
Explanation - Hypothesis is given when a question is identified and background research has been done. To validate the hypothesis, an experiment is carried out. While carrying out the experiment, analysis of the data is done where comparisons between the data are made.
While concluding, future work or research is mentioned. Hypothesis, analysis and conclusion are a series of steps that are carried out while doing a research. Therefore, these steps must be followed for proper result.
