Verified step by step guidance
1
Understand that post-transcriptional control refers to the regulation of gene expression after the transcription process, which is the synthesis of RNA from DNA.
Recognize that translational controls are part of post-transcriptional regulation. This involves mechanisms that influence the efficiency and rate at which mRNA is translated into proteins.
Consider changes to mRNA stability as another aspect of post-transcriptional control. This involves processes that affect how long an mRNA molecule remains intact and available for translation.
Acknowledge that the rate of mRNA translation can be regulated post-transcriptionally. This means that even after mRNA is produced, the cell can control how quickly or slowly it is translated into protein.
Understand that regulation of mRNA splicing is a form of post-transcriptional control. Splicing is the process of modifying the pre-mRNA transcript by removing introns and joining exons, and its regulation can affect the final mRNA product and thus gene expression.
