Answer:
ACAAACUAGAUGGUACCAGAUAAUAUAUAGGCC
Explanation:
Splicing is the process of modification of primary transcript and occurs after the process of transcription. During splicing, intervening non-coding nucleotide sequences called introns are removed. The exons are joined together to make a mature mRNA whose nucleotide sequence would code for protein. The introns (in lower case letters) will be removed from the given sequence of primary transcript during splicing.
Primary transcript: ACAAACUAGAUGGUACgugacagatacagaguagugaaguagCAGAUAAUAUAUAGGCC
After splicing: ACAAACUAGAUGGUACCAGAUAAUAUAUAGGCC
