Question 15
The higher protein abundance observed in the ACE20E allele compared to the wild-
type (ACE2*) allele is caused by altered regulation of gene expression at the post-
transcriptionalL level. Which of the following mechanisms are a likely explanation for
the abnormally high protein expression from the ACE20E allele? Select all that apply
C Increased length of the poly-A tail increases mRNA stability and translational
efficiency
Alternative splicing makes a shorter protein that is translated faster
Faster 5' capping increases MRNA stability and translational efficiency
Decreased microRNA expression reduces translational inhibition and ACE2
MRNA degradation
All of the above mechanisms are likely explanations
