WebIn eukaryotic cells like photoreceptors, gene expression is often controlled primarily at the level of transcription. However, that doesn't mean transcription is the last chance for regulation. Later stages of gene expression can also be regulated, including: RNA processing, such as splicing, capping, and poly-A tail addition WebProcessing of eukaryotic mRNA: Newly synthesized mRNA is called pre-mRNA. It is quite different from the mRNA that takes part in protein synthesis. At 5′ end of mRNA, a cap of …
