Answer:
One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.
One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.
Answer:
a. ΔG was negative.
Explanation:
The answer is a. ΔG was negative because, for a biochemical reaction to occur and provide energy for cellular metabolism, the Gibbs free energy ΔG = ΔH - TΔS < 0 , for spontaneity. If all terms on the right were to be negative, then ΔG = -ΔH - (-TΔS) = TΔS - ΔH and would only be less than zero if the absolute value of ΔH > absolute value of TΔS. If ΔG was positive as in C, the reaction would not be spontaneous and energy would have to be put into the biochemical reaction for it to occur. If all terms on the right were positive, then, ΔG = ΔH - TΔS < 0 when TΔS > ΔH , else ΔG > 0 and energy would have to be put into the biochemical reaction for it to occur, so its not spontaneous.
