You are studying bacterial cells and you find bacteria with a mutation that causes it
to produce non-functional ligase. If you allowed that cell to replicate once and then
you isolated the DNA from the two newly formed cells what would you expect to
find?
A. One longer single strand of DNA and many short single strands of DNA
B. Two longer single strands of DNA and many short single strands of DNA
C. Four longer single strands of DNA and many short single strands of DNA
D. Eight longer single strands of DNA and many short single strands of DNA
Choose the correct answer above and explain why you chose that answer. Your
explanation should discuss the replication of DNA in bacteria and the role of ligase in
DNA replication.
