The overwhelming majority of the mRNA expressed in the senescent leaf codes for proteases,lipases,and nucleases.

Question

Quizplus · Accepted Answer

This statement is true. Senescence, the process of aging in plants, is characterized by the breakdown of cellular components. Proteases, lipases, and nucleases are enzymes that catalyze the degradation of proteins, lipids, and nucleic acids, respectively. Therefore, it is not surprising that the majority of mRNA expressed in senescent leaves codes for these types of enzymes.
