Answer:
An amino acid activates the repressor so that the repressor binds to the operator and prevents transcription.
Explanation:
In an operon, promoter is followed by operator which is finally followed by the structural genes to be transcribed. RNA Polymerase binds to the promoter and initiates transcription. A repressor can negatively control the transcription process by binding to the operator so that the RNA Polymerase is not able to move forward and transcription is halted.
For example: in trp operon, tryptophan amino acid binds to the repressor molecule which leads to change in repressor's shape. The repressor is now able to bind to the operator and prevent transcription.
Explanation:
The passing of traits from parents to offspring is Inheritance (D).
Answer:
The answer is letter D
Explanation:
<em>The set point is the weight range in which your body is programmed to function optimally. Set point theory affirms that an indivual's body will fight to mantain that weight range. Evebody is biologically and genetically determined to weigh within a certain weight range. Set points will vary for each individual person. </em>
<em>Scientists estimate that the average person has a set point range about ten to twenty pound rage at which your body will be comfortable and not resist attempts to change.</em>
