The free end of the second RNA is uncapped and thus can be distinguished from genuine transcripts. This new RNA is recognized by an RNase called, in yeast, _ and in humans_ that is loaded onto the end of the RNA by another protein that binds the CTD of RNA polymerase.

According to Models of termination: torpedo and allosteric, which one is now the favored and why;
A. The Rat1 enzyme is very processive and quickly degrades the RNA in a 5’ -to-3’ direction, until it catches up to the still-transcribing polymerase from which the RNA is being spewed.
B. Termination depends on a conformational change in the elongating polymerase that reduces the processivity of the enzyme leading to spontaneous termination soon afterward.
