Answer

Post-translational Explanation 1. Identify Regulation Mechanism Protein X is regulated in the posterior pole by mechanisms that reduce its presence or activity. Transcriptional regulation, mRNA stabilization, and epigenetics typically affect gene expression levels, while post-translational modifications can alter protein function or stability. 2. Determine Most Likely Mechanism In this context, post-translational regulation is most likely responsible for reducing protein X activity specifically in the posterior pole, as it directly affects protein levels after synthesis.
