Answer:
Proteins are made up of monomer units connected together. These units are called amino acids. Each amino acid has a carbonyl group and an amine group. These two groups will link when the amino acids are added. Also, an amino acid has a specific R group that characterizes which type of amino acid it is.
Hope this helps.
<span>There needs to be an independent variable, a dependent variable, a constant, and a control group. The independent variable is the part that is manipulated. The dependent variable is affected by the independent variable. The constant is the part kept the same throughout all of the experiments. The control group is the normal group that is untreated.</span>
<h2>O
rigin of species.</h2>
Explanation:
Creationism is the most commonly accepted explanation of the origin of species.
- Creationism is a belief that biological similarities and differences are originated at creation.
- It is a theory which states that nature and its various aspects such as earth, life universe and humans are all created by God.
- Once the characteristics are set in the Creation it could not be changed.
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.
