Answer:
Each strand is made up of a sequence of four nucleotides, A, C, G, and T. The order of the nucleotide sequence encodes genetic information. Since the nucleotides pair in a predictable way — A with T, and C with G — each strand of the DNA is always complementary to the other.
Answer:
To eliminate alternative explanations for the results of an experiment.
Explanation:
The scientific experiments include all the procedure and observations that are observed during the experiments. The scientific experiments explain about the correct scientific information.
The particular hypothesis is tested by the scientific experiments. The experiments include controls and the variables. The variable that are used as hypothesis is not controlled and the results are matched directly. The other variables are controlled as this includes the other alternative explanation of the particular result.
Thus, the correct answer is option (C).
The substrate and the active site both need to fit together perfectly in order for the enzyme to work properly. If their shape is changed, typically through heat or a change in pH, the enzyme will not work.
