depends.... what's it all asking ? just that?

A theoretical protein, blue2, is coded for by the blu2 gene. This protein codes for a blue pigment used by the organism to protect it from damaging UV rays from sunlight. The enzyme alterase binding to the blu2 operator halts transcription of blue2. A blu2 operator mutation causes a conformational change that does not allow alterase to bind to operator.
What kind of gene regulation of blue2 is being used?

hiottmatt777 · Answer

1. Positive  2. Negative  3. Secondary  4. Splicing
I was thinking it would be a Negative gene regulation.

aziantime · Answer

In negative regulation a repressor protein binds to an operator to prevent a gene from being expressed. In positive regulation a transcription factor is required to bind at the promoter in order to enable RNA polymerase to initiate transcription. i agree with you ..i would choose 2. negative
