Answer:
C
Explanation:
I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
ALOT of words please lmk if it makes sense
<span>The answer is an
allergy. The allergy could cause the eyes
to be watery and to itch, sneezing and coughing, and a runny
nose. This is as a result of the mold fungi releasing numerous spores in the
air that enter the airways. Allergy is an immune response to the foreign bodies (spores) that have entered your
body. </span>
