Discuss what happens once transcription is complete.
What will be an ideal response?
Once transcription is complete, mRNA undergoes post-transcriptional processing. Enzymes in the nucleus excise segments of the mRNA known as introns, while leaving the segments known as exons. Thus, only exons are ultimately translated into the final protein product. While DNA remains in the nucleus, the messenger RNA carries the code out of the nucleus into the cytosol, where ribosomes on the rough endoplasmic reticulum are prepared for protein assembly. The complement of RNA transcripts produced when genes are "expressed" is referred to as the transcriptome.
