Homework Answers
I believe the correct answer to be:
Option A) DNA methylation.
As it can affect the process of transcription but once the transcription has happened, the methylation of DNA has no role in interfering with the mRNA or any post transcriptional process.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...
