Final answer:
Excessive binding of an alternative protein to the 3' UTR of an RNA can lead to decreased gene expression due to RNA degradation.
Step-by-step explanation:
When too much of an alternative protein binds to the 3' UTR of an RNA and causes it to degrade, the result would be decreased gene expression because RNA degradation prevents translation. The 3' UTR of an RNA plays a crucial role in regulating mRNA stability, and excessive binding of alternative proteins can lead to the breakdown of the RNA molecule, preventing it from being translated into protein. This can ultimately result in a decrease in gene expression.
