Post-Transcription Modification

Question 1

What is RNA splicing?

Answer 1

Post-transcription modification of RNA; allows more than one protein to be produced from one gene in eukaryotes

Question 2

Describe process of RNA splicing

Answer 2

1) Gene is transcribed, resulting in pre-MRNA
2) All introns (non coding region) and some exons (coding region) are removed
3) Remaining genes are rejoined by enzyme complexes called spliceosomes —> same exons can be joined to produce diff versions of mature functional RNA
