During protein synthesis, when are introns removed?

Question

Quizplus · Accepted Answer

After transcription results in mRNA production, the mRNA must undergo preparation for translation processes within the endoplasmic reticulum.Among these posttranscriptional processes are the removal of introns, the capping of the 5-prime end, and the addition of a polyadenosine tail to the 3-prime end of the mRNA.After the protein is produced during translation, posttranslational processing involves the change in the protein to its active form.
