A sample's RNA-ligating activity is lost after RNase treatment, preserved after protease treatment, and restored when the original RNA sequence is added back. Which conclusion is best supported?
A
The activity cannot involve sequence-specific molecules.
B
The activity most likely depends on a specific RNA molecule with catalytic function.
C
The activity proves that all early RNA molecules fully self-replicated.
D
The activity most likely depends on a protein that survives RNase but not protease.
