RNA Splicing
The removal of introns and some exons before translation, and the subsequent joining of exons by spliceosomes for translation.

Pre-mRNA the mRNA that is transcribed directly from the DNA before it is modified.

1. Once transcription has taken place, the Pre-mRNA must be modified before translation.

2. The introns are removed from the Pre-mRNA, and sometimes a few exons.

3. The exons to be transcribed are then joined together by enzyme complex’s known as ‘Spliceosomes’ to produce functional mRNA for translation.

Spliceosomesenzyme complexes that act on Pre-mRNA, joining exons together after the removal of introns.

The spliceosomes can join the exons together in a huge variety of ways. This means a single gene can produce several versions of functional mRNA, and so form different proteins.

(Theres my notes on it from a-levels)
