Question
What is splicing? Why is splicing necessary in eukaryotic genes?
✓
Answer
The process by which non-coding regions (intron) on hnRNA are removed and coding regions (exon) are joined to produce mRNA is called splicing. Splicing is necessary in eukaryotes to remove the non-coding introns from hnRNA to produce a meaningful functional mRNA. Prokaryotes do not have introns in the mRNA.
