Chapter 14: Gene Transcription and RNA Modification
... These processes can be divided into two general categories. The first form of modification is a chemical change to the RNA transcript. This is usually in the form of 5′ capping or 3′ polyA tailing, and sometimes even editing changes that alter the base sequence after it has been synthesized. The sec ...
