mRNA is degraded more quickly than rRNA in the cell. Why?
O Ribosomal RNA is a component of ribosomes, which must remain functional for long periods of time.
O Messenger RNA forms a complex with the ribosome, thus stabilizing the mRNA.
O The rRNA, being larger than mRNA on average, is intrinsically less stable.
O Messenger RNA is made in low copy numbers, thus requiring it to be longer lived than rRNA.
