D
RNA splicing
Verified step by step guidance1
Understand that gene expression involves multiple stages: transcription, RNA processing, translation, and post-translation.
Identify that post-transcriptional control refers to mechanisms that regulate gene expression after the transcription of DNA to RNA.
Consider RNA splicing, which is the process of modifying the pre-mRNA transcript by removing introns and joining exons, as a post-transcriptional control mechanism.
Recognize mRNA degradation as a process that controls the stability and lifespan of mRNA molecules, affecting how much protein is produced, and is a form of post-transcriptional regulation.
Note that protein folding occurs after translation, which is the process of synthesizing proteins from mRNA, and thus is not a control mechanism of gene expression after transcription.
