Answer #2

Adding all the exons together plus 5’UTR, 3’UTR and polyA tail we get 329bp

Explanation:

Introns are removed from the pre-mRNA during processing.

Primary RNA transcript Exon 1 Intron Exon 2 Intron Exon 3 RNA processing Spliced RNA o,Exon 1 Exon 2 Exon AAAAAAA Poly-A tail

Answer #1

The poly(A) tail is important for the nuclear export, translation and stability of mRNA. The tail is shortened over time, and, when it is short enough, the mRNA is enzymatically degraded.
