In the hierarchy of levels of gene regulation, in what order do the following levels of regulation take place? (1) post-translational modification
(2) RNA processing
(3) transcription
(4) chromatin remodeling

Question

Quizplus · Accepted Answer

Chromatin remodeling occurs first in the hierarchy of levels of gene regulation, as it involves changing the accessibility of DNA to transcription factors and other regulatory proteins. Transcription occurs after chromatin remodeling, allowing for the synthesis of RNA. RNA processing, which includes splicing and other modifications, occurs after transcription. Finally, post-translational modification occurs after the RNA is translated into protein. Therefore, the correct order is (4)-(3)-(2)-(1).
