Answer:
The normal role of this control element can be that of a negative modulator or regulator
Explanation:
For example, the lactose operon in the bacteria <em>Escherichia coli</em> is negatively regulated. In lactose absence a represor protein is produced, which inserts in the DNA operator site blocking transcription of structural genes. if for example a mutation affects the synthesis of this repressor, expression of structural genes will increase with no regulation.
A mutation in the DNA operator site that avoids insertion of the repressor, too.
A mutation in the gene that codes for the repressor, will also do the job
Answer:
the second one
Explanation: IN the text it literally states it explicitly.
