You are studying different DNA replication defects found in different populations of lab-grown E. coli bacteria. Consider the following observations, identify what could be going wrong, and justify your answer using information we learned in class:

No DNA replication is occurring in your first E. coli population (1pt)

The new DNA strands are breaking apart easily after replication in your second E. coli population (1pt)

Double strand breaks are occurring on the template strand during replication in their E. coli population (1pt)
