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.
The answer is C. All of these different environments require a wider variety of adaptations.
Answer:
Explanation:
Honey-colored eyes A is dominant over blue-colored eyes a.
A homzygous honey-colored male (AA) had a baby with blue-eyed female (aa).
AA x aa
Offspring Aa Aa Aa Aa
1. Since A is dominant over a, <u>all the expected offspring would have honey-color eyes with Aa genotype.</u>
2. The genotype of the homzygous honey-color eyes father would be AA while that of the blue-eye mother would be aa.
