One of the problems with DNA replication is that, due to bi-directional replication, it is very difficult to replicate the Chromosome all the way to the end.  This is called the “end replication problem”.  In one short sentence each, answer the following:   a) Why do bacteria that need to replicate almost infinitely (since binary fission is their method of reproduction) not have to deal with the end replication problem? b) How do cells that divide, but not extensively, ensure that the end replication problem does not cause critical genes to become missing when the cell divides a limited number of times? c) How do cells like stem cells that must divide a large number of times overcome the end replication problem?

All of the following are functions of various DNA polymerases (these could include both DNA polymerase III and DNA polymerase I) except:
