<span>a serious mutation in ribosomal RNA gene is worse. the mutated ribosomes may lose their abilty to bind to messenger RNAs through Shine Dalgarno Sequences. they may also present wrongly placed E,P and A sites to the messenger RNA. this will lead to lethal results ranging from abnormal polypeptide formation to no formation at all.</span>
Answer:
I believe it's a Core-fusion star.
Explanation:
The operon is effectively the center of transcriptional control. In addition to its main structural genes, the operon houses an operator and a promoter. In front of the promoter lies a regulatory gene that produces repressor proteins. When a repressor is in its active state, it binds to the operator.
Hope this helped.
