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()()()()()

(4)-(3)-(2)-(1)

Explanation:

Gene expression is regulated at many levels:

Chromatin remodeling regulation includes altered histone modifications such as methylation which can regulate gene expression (up or down).Transcription is regulated via transcriptional factors and specificity factors such as repressors and activators.RNA processing can be regulated through the alternative splicing (different introns can be excised and combinations of different exons connected)post-translational modification refers to modification of proteins after being synthesized.

The correct answer is b

I’m not exactly sure what your trying to ask, but if it’s how an organelle is similar to a body system or a part a nucleus is like a in function. but i don’t fully understand what you’re trying to ask
