The dispersive model's prediction a. 14N/14N (top), 14N/15N (intermediate) b. 14N/14N (top), 15N/15N (bottom) this the banding patterns after the two rounds of replication. 14N/15N b. 14N/15N
c. 14N/14N (top), 15N/15N (bottom). It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.
