Introns are non-coding sequences in pre-mRNA that are removed before the mRNA leaves the nucleus. This process is essential for proper protein synthesis.
Introns are intervening sequences within a pre-mRNA molecule that do not code for proteins and are removed during RNA processing by a spliceosome. They are considered as non-coding DNA and are removed to form mature mRNA.
Exons, on the other hand, are expressing sequences within a pre-mRNA molecule that are spliced together once introns are removed to form mature mRNA molecules that are translated into proteins.
Before mRNA leaves the nucleus, these introns must be removed during RNA processing to ensure correct protein synthesis.
