Question
The regulation of mRNA decay relies heavily upon deadenylases and decapping enzymes. Explain how these classes of enzymes are critical to initiating mRNA decay.
Step 1
mRNA structure: To understand the role of deadenylases and decapping enzymes in mRNA decay, it is essential to know the structure of mRNA. Mature mRNA molecules consist of a 5' cap, a coding region, and a 3' poly(A) tail. The 5' cap and 3' poly(A) tail protect the Show more…
