Question

Quizplus · Accepted Answer

A promoter mutation results in reduced or absent production of the globin chain, as it affects the binding of RNA polymerase and other transcription factors to the promoter region, thereby reducing the transcription of the gene. This ultimately leads to reduced or absent production of the globin chain.
