Question
Imagine you are going to label a gene associated with apoptosis in
Symbiodiniaceae with a Yellow Fluorescent Protein (YFP). To
generate the YFP, you know the pre-MRNA looks as follows:
Unspliced YFP premature mRNA
Сap
5' UTR
Exon 1
Intron
Exon 2
Intron
Exon 3
3' UTR
Poly-A tail
If Exon 2 is also required for mRNA stability, what can be predicted
from the possible spliced alternative isoforms formed?
One of the isoforms will not have a poly-A tail
O The alternative splicing of YFP pre-MRNA prevents 5'-capping
The MRNA isoform without Exon 2 will be degraded faster than the other
isoform
Exon 2 will be added to isoform B later to correct the mistake in splicing
The protein translated from one of the mRNA isoforms will possess an
additional functional domain
