The answer is <span>C.silent.
Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.

Answer: Yes
Explanation: In order to go to the right end you must be searched first anyone tells you otherwise.
Answer: The correct answer is D. ATP provides energy coupling between exergonic and endergonic reactions.
ATP hydrolysis is an exergonic reaction, as a large amount of energy is released when this molecule is hydrolyzed. ATP is converted into ADP ( adenosine diphosphate) and inorganic phosphate. The energy released in this reaction is utilized by the endergonic reactions ( which require energy) such as photosynthesis.
Thus, the central role that ATP in cellular metabolism is that it provides energy coupling between exergonic and endergonic reactions.
