WebCircular DNA also circumvents the Hayflick limit (thus allowing it to be "immortal"), which is the number of times a cell population can divide before it stops, presumably due to the shortening of telomeres, the sequences at the end of the chromosomes. Since circular DNA lacks telomeres, it does not get shorter with each replication cycle.
