A gene encodes a pre-mRNA with 5 exons and 4 introns.  A mutation eliminates the 3’ splice site from intron 3. What exons would be found in the mRNA after splicing was completed?

In eukaryotes, what does the mRNA transcript contain? 

In eukaryotic cells, the initial RNA transcript (pre-mRNA) contains non-coding segments called [ Select ] spliceosomes promoters exons introns polymerase that intervene between coding regions. Before the RNA leaves the nucleus, a large protein-RNA complex called the [ Select ] introns polymerase exons ribosomes spliceosomes removes these non-coding parts and joins the coding regions, known as [ Select ] promoters spliceosomes polymerase exons introns together. This process allows a single gene to encode multiple different proteins depending on which segments are treated as coding.
