Post-Transcriptional Processing and Introns/Exons Quiz

Post-transcriptional processing is a series of modifications that occur to RNA molecules after they have been transcribed from DNA.

Split genes are genes that contain introns, which are non-coding sequences of DNA, and exons, which are coding sequences of DNA.

Introns are non-coding sequences of DNA, while exons are coding sequences of DNA.
