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?

Positive
Negative
Secondary
Splicing

Negative regulation

Explanation:

The enzymes involved are:

blue 2 protein

enzyme alterase binds to blue 2 operator alters blue 2 transcription.

Mutation in blue 2 operator detest alterase activity.

In negative regulation the alterase ( repressor) binds to the blue gene operator and prevents the transcription of blue gene and hence altering the blue 2 protein production.

After mutation in blue 2 gene operator due to confirmational change alterase does not bind to operator and hence blue 2 gene gets transcribe when transcription factors bind to promoter.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
