Are exons removed?
No, introns are removed at the time of processing of RNA as they are non-coding sequences. Further reading: RNA Splicing... View Article
What occurs during splicing?
Splicing takes place in the nucleus. During splicing, introns are removed from hnRNA and exons are joined together. Further reading:... View Article
