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.
