Why Are Ribonucleases That Digest Mature Messenger RNA a Necessary

question 1

Multiple Choice

Why are ribonucleases that digest mature messenger RNA a necessary part of protein synthesis?

• A)These enzymes prevent overexpression of critical proteins.
• B)Without ribonucleases, messenger RNA could leave one cell type and lead to excessive protein synthesis in a different cell type.
• C)When ribonucleases degrade RNA, the degradation products are recycled, making protein synthesis more energy efficient.
• D)The activity of these enzymes promotes increased translation of individual messenger RNAs so that fewer RNA molecules are needed for protein production.
