By counting the number of sites to which ORC binds, we can estimate that there are about 400 origins of replication in the yeast genome. This means that the average length of a replicon is -35,000 bp.

In wild-type genes, RNA polymerase II terminates transcription at any one of multiple possible sites within about

2 kb of the polyadenylation signal. When the polyadenylation signal is mutated, RNA polymerase II does not terminate transcription, but continues transcription until the next poly(A) site.
