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
Hey! I'm pretty sure this is chemistry instead of biology haha
But anyways, a typical carbon atom can form up to 4 covalent bonds!
I would say oxygen because respiration is breathing mechanically.
A sperm and egg combine to make a zygote. (or fertilized egg)
So, the answer would be "A".
I hope this helps!
